Various approaches for optimizing the first hyperpolarizability (beta) are discussed. It is shown, computationally that an optimal degree of bond-length alternation in polyenic molecules is required to maximize beta. The aromaticity of the pi-electron system is an important factor in determining bond-length alternation. An example of a molecule whose pi-electron system is not strongly aromatic in the neutral canonical resonance form and has large beta is described. The second hyperpolarizability (gamma) is correlated with bond-length alternation and exhibits both positive and negative peak as a function of this parameter. Finally, the organic salt, 4-N,N-dimethylamino-4'-N'-methylstilbazolium toluene-p-sulfonate (DAST), which has an extremely large macroscopic second-order optical nonlinearity, is discussed.

Thirty-eight elderly men and women (ages 60-82 yr) were assigned to endurance exercise training (N = 29) or to control (N = 9) groups. Resting plasma levels of adrenocorticotropic hormone, vasopressin, aldosterone, norepinephrine, epinephrine, sodium, potassium, and protein were measured at the start (T1) and end (T2) of 26 wk of training. PV measurement was performed using the Evan's blue dye technique. Endurance training consisted of uphill treadmill walking or stairclimbing exercise 3 times.wk(-1), 30-45 min.d(-1), at 75-84% of maximal heart rate reserve. The exercise group increased VO2max by 11.2% (P less than or equal to 0.05) and increased resting PV and BV by 11.2% and 12.7% (P less than or equal to 0.05), respectively. Hormone and electrolyte levels in the exercise group remained unchanged; all variables were unchanged in the control group. These results are similar to findings in younger individuals. Because plasma hormone concentrations were maintained despite a chronically elevated BV, endurance training in healthy, elderly subjects may be associated with a resetting of volume receptors.

The cross-sectional sample consisted of 1,499 healthy men ages 25-70 yr. The 156 men of the longitudinal sample were from the same population and examined twice, the mean time between tests was 4.1 (+/-1.2) yr. Peak oxygen uptake was determined by indirect calorimetry during a maximal treadmill exercise test. The zero-order correlations between VO(2)peak and %fat (r = -0.62) and SR-PA (r = 0.58) were significantly (P < 0.05) higher that the age correlation (r = -0.45). Linear regression defined the cross-sectional age-related decline in VO2peak at 0.46 ml kg(-1).min(-1) yr(-1). Multiple regression analysis (R = 0.79) showed that nearly 50% of this cross-sectional decline was due to %fat and SR-PA, adding these lifestyle variables to the multiple regression model reduced the age regression weight to -0.26 ml.kg(-1) min(-1).yr(-1) Statistically controlling for time differences between tests, general linear models analysis showed that longitudinal changes in aerobic power were due to independent changes in %fat and SR-PA, confirming the cross-sectional results.

The DS process replaced the fine, equiaxed NiAl grain structure of the PC composites with an oriented grain structure comprised of large columnar NiAl grains aligned parallel to the fiber axis, with fibers either completely engulfed within the NiAl grains or anchored at one to three grain boundaries. The load-displacement behavior during the pushout test exhibited an initial ''pseudoelastic'' response, followed by an ''inelastic'' response, and finally a ''frictional'' sliding response. The fiber-matrix interfacial shear strength and the fracture behavior during fiber pushout were investigated using an interrupted pushout test and fractography, as functions of specimen thickness (240 to 730 mu m) and fabrication technique. The composites fabricated using the PC and the DS techniques had different matrix and interface structures and appreciably different interfacial shear strengths. In the DS composites, where the fiber-matrix interfaces were identical for all the fibers, the interfacial debond shear stresses were larger for the fibers embedded completely within the NiAl grains and smaller for the fibers anchored at a few grain boundaries. The matrix grain boundaries coincident on sapphire fibers were observed to be the preferred sites for crack formation and propagation. While the frictional sliding stress appeared to be independent of the fabrication technique, the interfacial debond shear stresses were larger for the DS composites compared to the PC composites. The study highlights the potential of the DS technique to grow single-crystal NiAl matrix composites reinforced with sapphire fibers, with fiber-matrix interfacial shear strength appreciably greater than that attainable by the current solid-state fabrication techniques.

Steady and transient thermocapillary flows were investigated in a 10 cm dia. circular container filled with 10 Cs silicone oil. The velocity and temperature fields were studied in detail under various conditions. It is shown in this paper how the Marangoni number affects the velocity field. A numerical analysis of the flows was also conducted and its results were compared to the experimental data. Good agreement is shown. C1 NASA,LEWIS RES CTR,CLEVELAND,OH 44135.

Both oscillatory and stationary instabilities are considered for a wide range of parameters. It is shown that only stationary instability is possible when surface tension at the colder interface is lower than that at the hotter one. Oscillatory instability tends to disappear and to be replaced by the stationary instability with increase of the Prandtl number and decrease of surface tension at the colder interface.

The IDGE measured dendritic growth rates, tip radii, and crystal morphologies of ultra-pure succinonitrile [CN-(CH2)(2)-CN] at supercoolings in the range from 0.05 - 2.0 K. Data taken in the form of slow-scan binary digitized images telemetered to the ground from orbit in near-real time, combined with the IDGE terrestrial data set, provide the first quantitative assessment of various theories on dendritic solidification and the effects of convection on dendritic growth.

Time series of the area-averaged precipitation [P] over the Asian-Australian (AA) monsoon (60 degrees E-120 degrees W), and the extra-AA monsoon (120 degrees W-60 degrees E) hemispheres were used in describing the variations. A distinct seesawlike intraseasonal variation of precipitation between these two hemispheres emerges from the two time series. Two intraseasonal (30-60 and 12-24 day) modes stand out in the spectral analysis of the two [P] time series. The 30-60-day mode is well known, while the 12-24-day mode is identified here for the first time. Using data generated by the Global Data Assimilation System of the National Meteorological Center, an effort was made to investigate the characteristics of the 12-24-day mode of global precipitation via potential functions for the 200-mb wind, water vapor transport, and precipitation. It is found that the 12-24-day mode exhibits a wavenumber 1 structure and propagates eastward. The seesaw intraseasonal variation of precipitation between the AA and extra-AA monsoon hemispheres is caused not only by the 30-60-day mode but also by the 12-24-day mode.

Results from a month long field project in Jerusalem in June-July 1994 demonstrate the usefulness of the new techniques on inscribed soft media and ostraca. The imaging approach is effective and useful on frescoes, mosaics, ink inscriptions on plaster, colored textiles and illuminated manuscripts. Most of the examples will be drawn from text material, as these are the objects we have had the most access to for this study, although we have examples from some of the other areas as well. The techniques presented here are not generally suitable for imaging for cataloguing or archival purposes. They are meant for objects that are difficult to interpret or reassemble or conserve.

It is based on the standard diffusion-convection theory of solar modulation. Estimates of the modulation potential based on fitting this theory to observed spectral measurements from 1954 to 1989 are correlated to the Climax neutron counting rates and to the sunspot numbers at earlier times taking into account the polarity of the interplanetary magnetic field at the time of observations. These regression lines then provide a method for predicting the modulation at later times. The results of this model are quantitatively compared to a similar Moscow State University (MSU) model. These model cosmic ray spectra are used to predict the linear energy transfer spectra, differential energy spectra of light (charge less than or equal to 2) ions, and single event upset rates in memory devices. These calculations are compared to observations made aboard the Space Shuttle. RP BADHWAR, GD (reprint author), NASA,LYNDON B JOHNSON SPACE CTR,HOUSTON,TX 77058, USA.

Indeed, the number of particles and the absorbed energy behind most shield materials increases as a function of shield thickness. The modification of the galactic cosmic ray composition upon interaction with shielding is the only effective means of providing astronaut protection. This modification is intimately connected with the shield transport properties and is a strong function of shield composition. The systematic behavior of the shield properties in terms of microscopic energy absorption events will be discussed. The shield effectiveness is examined with respect to conventional protection practice and in terms of a biological endpoint: the efficiency for reduction of the probability of transformation of shielded C3H10T1/2 mouse cells. The relative advantage of developing new shielding technologies is discussed in terms of a shield performance as related to biological. effect and the resulting uncertainty in estimating astronaut risk.

At present, there is no suitably accurate theory for predicting nuclear fragmentation cross sections for all collision pairs and energies of interest in space radiation protection, Typical cross-section differences between theory and experiment range from about 25 percent to a factor of two. The resulting errors in transported flux, for high linear energy transfer (LET) particles, are comparable to these cross-section errors. In this overview, theoretical models of heavy ion fragmentation currently used to generate input data bases for cosmic-ray transport and shielding codes are reviewed. Their shortcomings are discussed. Further actions needed to improve their accuracy and generality are presented. RP TOWNSEND, LW (reprint author), NASA,LANGLEY RES CTR,HAMPTON,VA 23681, USA.

However, there are also a substantial fluxes of H-2 and He-3, In this paper we describe theoretical models based on quantum multiple scattering theory for the description of light ion nuclear interactions. The energy dependence of the light ion fragmentation cross section is considered with comparisons of inclusive yields and secondary momentum distributions to experiments described. We also analyze the importance of a fast component of lights ions from proton and neutron induced traget fragmentation, These theoretical models have been incorporated into the cosmic ray transport code HZETRN and will be used to analyze the role of shielding materials in modulating the production and the energy spectrum of light ions.

In this work quantum mechanical optical model methods for estimating cross sections for HZE particle fragmentation by hydrogen targets are presented. The cross sections are calculated using a modified abrasion-ablation collision formalism adapted from a nucleus-nucleus collision model. Elemental and isotopic production cross sections are estimated and compared with reported measurements for the breakup of neon, sulphur, and iron, nuclei at incident energies between 400 and 910 MeV/nucleon.

The storm evolution is modeled after the November 1960 event, and the solar proton flux evolution is taken from the August 1972 solar proton event. The effects of a strong magnetic shock, such as was observed during the October 1989 event, is also modeled. The statistics on hourly average storm fields for the last forty years reveal that the largest geomagnetic storms approach a Dst value of -500 nanotesla at the storm peak. Similarly, one of the largest satellite-measured proton flux (> 10 MeV) for space exposures is the event of August 1972. The effects of orbit progression (advance of the line of nodes) is examined for the above conditions to study the variation of exposures under differing times of occurrence of the solar proton peak intensity, attainment of geomagnetic storm maximum, and the location of the line of nodes of the last geomagnetically protected orbit. The impact of the inherent inhomogeneity of the space station module is examined as a limiting factor on exposure with regard to the need of additional parasitic shielding.

Few observations of increases in particle populations have been reported. This is particularly true for effects in low Earth orbit, where manned spaceflights are conducted. This paper reports the existence of a second proton belt and it's subsequent decay as measured by a tissue-equivalent proportional counter and a particle spectrometer on five Space Shuttle flights covering an eighteen-month period. The creation of this second belt is attributed to the injection of particles from a solar particle event which occurred at 2246 UT, March 22, 1991. Comparisons with observations onboard the Russian Mir space station and other unmanned satellites are made. Shuttle measurements and data from other spacecraft are used to determine that the e-folding time of the peak of the second proton belt. It was ten months. Proton populations in the second belt returned to values of quiescent times within eighteen months. The increase in absorbed dose attributed to protons in the second belt was approximately 20%. Passive dosimeter measurements were in good agreement with this value. RP BADHWAR, GD (reprint author), NASA,LYNDON B JOHNSON SPACE CTR,HOUSTON,TX 77058, USA.

TWOS is a special-purpose operating system designed to run parallel discrete event simulations with maximum efficiency on parallel or distributed computers. The parallelization process is described, and a formula is derived for the maximum possible speedup using this technique. For the benchmark used, a speedup of 8 was obtained while running on 10 nodes of a BBN GP1000 parallel computer, indicating that this approach is a useful way of parallelizing cascade-correlation.

The light curve at 2650 Angstrom constructed with the 11 best images exhibits a variable trend with a factor less than or equal to 2 enhancement of the flux in about 3 hours, Simultaneous ground based observations show an optical flux variability of smaller amplitude, but correlated with the UV light curve without any apparent lag. The radio light curve is nearly constant. The UV emission state is the weakest observed in 15 years for this flaring blazar, being a factor of less than or similar to 20 lower than the maximum recorded one.

Irrespective of decay mode, for tau(nu) greater than or similar to 300 sec the mass of the tau neutrino must be either approximately 30 MeV or less than 0.4 MeV (Majorana), 15 keV (Dirac). If the dominant decay mode includes electromagnetic daughter products, the mass must be less than 0.4 MeV (Majorana or Dirac) provided tau(nu) greater than or similar to 2.5 x 10(-12) sec, 15 keV (Dirac) provided tau(nu) greater than or similar to 10(-6) sec(m(nu)/MeV). A tau neutrino of mass between 1 MeV and 30 MeV can have a host of interesting astrophysical and cosmological consequences: relaxing the big-bang nucleosynthesis bound to the baryon density and the number of neutrino species, allowing big-bang nucleosynthesis to accommodate a low (less than 22%) He-4 mass fraction or high (greater than 10(-4)) deuterium abundance, improving significantly the agreement between the cold dark matter theory of structure formation and observations, and helping to explain how type II supernovae explode. Exploring the MeV mass range not only probes fundamental particle physics, but also interesting astrophysical and cosmological scenarios. C1 UNIV CHICAGO,DEPT PHYS,CHICAGO,IL 60637.

A companion use-it-or-lose-it permit provision has had the perverse effect of increasing fishing effort during times of declining stocks. Despite its unfavorable short-term prospects, the fishery has the potential to be very lucrative for a small number of boats over the long term. This paper introduces a dramatically different management regime that would create ownership rights in a private management corporation for the current limited-entry permit holders. This corporation would function within a renewable operating contract with the government to protect the public interest in the conservation of the lobster population and its associated ecosystem.

The CDQ program is of interest as a limited access management system which explicitly recognizes the special needs of communities as distinct from business firms or individuals, while achieving some of the benefits, as well as costs, of other programs such as limited licensing and individual transferable quotas. This article describes the program, reviews some of its benefits and costs, notes the recent creation of CDQs for other species, and suggests the importance of CDQs for future fisheries management.

This simplifies subsequent image processing steps for applications such as image restoration or correlation for pattern recognition. One particularly common form of multiplicative noise is speckle, for which the logarithmic operation not only produces additive noise, but also makes it of constant variance (signal-independent). I examine the optical transmission properties of some bacteriorhodopsin films here and find them well suited to implement such a pointwise logarithmic transformation optically in a parallel fashion. I present experimental results of the optical conversion of speckle images into transformed images with additive, signal-independent noise statistics using the real-time photochromic properties of bacteriorhodopsin. I provide an example of improved correlation performance in terms of correlation peak signal-to-noise for such a transformed speckle image.

The semi-major axis monitors the effect of nonconservative forces, and the eccentricity is particularly affected by solar radiation pressure. The conservative forces of the geopotential and Earth and ocean tides influence the behavior of the inclination and the right ascension of the ascending node. The contrasting effects of these perturbations on the longterm evolution of the satellites LAGEOS I (circular, 12,000 km semi-major axis, 109 degree inclination orbit) and LAGEOS II (circular, 12,000 km semi-major axis, 53 degree inclination orbit), as well as ETALON I and ETALON II (both of which are in circular, 25,500 km semi-major axis 65 degree inclination orbits) will be presented. The major difference between the evolution of the LAGEOS satellites' orbits is caused by the difference in inclinations between LAGEOS I and LAGEOS II. There is no such contrast in the orbits of ETALON I and II and the observed dissimilarity in their response to direct solar radiation pressure must be caused by satellite area, mass or reflectivity differences. Although both LAGEOS satellites have observed solar radiation coefficients of about 1.13, using a 42 cm radius and a mass of 1346 kg for the ETALON satellites, the coefficient of solar radiation pressure for ETALON I has been determined to be 1.22, and 1.25 for ETALON II. The capability of these satellites to define a reference frame for Earth orientation measurements will improve with the models for their orbital evolution.

Tracking of these targets is a low priority for most of the ground stations due to the present mandatory support of missions with no alternative tracking. The available data is sparse and concentrated primarily on the first of the two spacecraft, GPS-35 (PRN 5). Despite this, analysis of this data set indicates that there is great potential for engineering and scientific experiments in a synergistic application of Satellite Laser Ranging (SLR) and radiometric GPS techniques.

TDRSS currently consists of five geosynchronous spacecraft and the White Sands Complex (WSC) at White Sands, New Mexico. The Bilateration Ranging Transponder (BRT) System (BRTS) supports range and Doppler measurements for each TDRS using standard user tracking services. These measurements are used to generate well-determined ephemerides for the TDRSs. TDRSS provides S-band and Ku-band services through the single access (SA) antennas and S-band services through the S-band multiple access (SMA) phased array. TDRSS is capable of supporting coherent range and two-way Doppler tracking as well as noncoherent one-way return-link and one-way forward-link Doppler tracking of user spacecraft. Accurate one-way return-link tracking, which can use SMA, the most available TDRSS resource, requires a stable oscillator onboard the user spacecraft as the source of frequency. Two-way and one-way return-link tracking measurements are used for ground orbit determination for navigation and precise positioning; one-way forward-link tracking is used for autonomous onboard navigation with achievable accuracies better than those of the Global Positioning System (GPS) Precise Positioning System (PPS). This overview will discuss the various tracking and navigation capabilities of TDRSS, as well as many of the operational and research applications that have been conducted far missions such as Landsat-4, Ocean Topography Experiment (TOPEX)/Poseidon (T/P), Cosmic Background Explorer (COBE), and Extreme Ultraviolet Explorer (EUVE).

The TONS I operational system processes Doppler data derived from scheduled forward-link S-band services to provide onboard orbit and frequency determination and time maintenance. TONS I is implemented using a stable onboard frequency reference, a Doppler measurement capability in the user transponder, and onboard navigation/signal acquisition software. The success of the TONS experiment (1992/1993), which was implemented on the Explorer Platform/Extreme Ultraviolet Explorer (EP/EUVE) spacecraft, demonstrated the flight readiness of TONS I. TONS II-A provides the user with additional Doppler data derived from an S-band beacon signal, available approximately 80 percent of the time.

The geostationary Tracking and Data Relay Satellite System (TDRSS) satellites are providing the operational tracking and communication support for this mission. The TDRSS Doppler data are of high precision (0.3 mm/s nominal noise levels). Unlike other satellite missions supported operationally by TDRSS, T/P has high quality independent tracking which enables absolute orbit accuracy assessments. In addition, the T/P satellite provides extensive geometry for positioning a satellite at geostationary altitude, and thus the TDRSS-TIP data provides an excellent means for determining the TDRS orbits. Are lengths of 7 and 10 days with varying degrees of T/P spacecraft attitude complexity are studied. Sub-meter T/P total positioning error is achieved when using the TDRSS range-rate data, with radial orbit errors of 10.6 cm and 15.5 cm RMS for the two arcs studied. Current limitations in the TDRSS precision orbit determination capability include mismodeling of numerous TDRSS satellite-specific dynamic and electronic effects, and in the inadequate treatment of the propagation delay and bending arising from the wet troposphere and ionosphere.

A group of 21 normal, healthy volunteers (11 male and 10 female) were scanned six times, receiving one pencil-beam and one array whole-body scan on three occasions approximately 1 week apart. The following combinations of scan modes and analysis software were used: pencil-beam scans analyzed with Hologic's standard whole-body software (PB scans); the same pencil-beam analyzed with Hologic's newer ''enhanced'' software (EPB scans); and array scans analyzed with the enhanced software (EA scans). Precision values (% coefficient of variation, %CV) were calculated for whole-body and regional bone mineral content (BMC), bone mineral density (BMD), fat mass, lean mass, %fat and total mass. In general, there was no significant difference among the three scan types with respect to short-term precision of BMD and only slight differences in the precision of BMC. Precision of BMC and BMD for all three scan types was excellent: <1% CV for whole-body values, with most regional values in the 1%-2% range. Pencil-beam scans demonstrated significantly better soft tissue precision than did array scans. Precision errors for whole-body lean mass were: 0.9% (PB), 1.1% (EPB) and 1.9% (EA). Precision errors for whole-body fat mass were: 1.7% (PB), 2.4% (EPB) and 5.6% (EA). EPB precision errors were slightly higher than PB precision errors for lean, fat and %fat measurements of all regions except the head, although these differences were significant only for the fat and % fat of the arms and legs. In addition EPB precision values exhibited greater individual variability than PB precision values. Finally, absolute values of bone and soft tissue were compared among the three combinations of scan and analysis modes. BMC, BMD, fat mass, %fat and lean mass were significantly different between PB scans and either of the EPB or EA scans. Differences were as large as 20%-25% for certain regional fat and BMD measurements. Additional work may be needed to examine the relative accuracy of the scan mode/software combinations and to identify reasons for the differences in soft tissue precision with the array whole-body scan mode.

In general, both tidewater and non-tidewater glaciers in the area have receded during the last century, but the rates of recession are quite variable, especially in the case of the tidewater glaciers. Available average air temperature data from nearby meteorological stations show a general warming trend, especially over the last 20 years. Such a warming trend may help to explain recession of the non-tidewater glaciers of the area. Comparison of September Landsat multispectral scanner imagery from 1973 and 1986 shows that the amount of vegetation increased significantly and rapidly as glaciers receded. The vegetation within a Landsat subscene covering Muir Inlet increased about 86% during the 13-year period. The once-impressive Muir Glacier, a tidewater glacier, has receded dramatically since the late 1800s. Satellite measurements show that the terminus retreated > 7.3 km between 1973 and 1992. Work accomplished by researchers earlier in this century has been extended using satellite techniques, allowing us to study glacier changes quantitatively in the entire Glacier Bay region over the past two centuries.

We have established that the ratio, R(T), of hemispherical total emissivity ET(T) to constant-pressure specific heat c(p)(T) can serve as an indicator which is sensitive to any changes in short range atomic order in undercooled metallic melts. R(T)equivalent to epsilon(T)/c(p)(T) values for nickel, zirconium, and silicon have been obtained using the high temperature electrostatic levitator while the levitated melts were undergoing purely radiative cooling into the deeply undercooled region. R(T) plots for undercooled liquid nickel and zirconium indicate no significant change in short-range structure From their melting temperatures to 15% undercooling. In contrast, liquid silicon shows marked short-range structural changes beginning above its melting temperature and extending throughout the undercooled region. The short-range structure of liquid silicon is related to the highly-directional covalent bonding which characterizes its solid form. The nickel and zirconium data show that epsilon T varies linearly with T, in support of metal emissivity theories.

A primary characteristic of observed foreshock electrons is that their velocity distributions are spatially structured in a systematic way depending on distance from the magnetic field line which is tangent to the shock. There are two interrelated aspects to explaining the structure of velocity distributions in the foreshock, one involving the acceleration mechanism and the other, propagation from the source to the observing point. First, the source distribution of electrons energized by the shock must be determined along the shock surface. Proposed acceleration mechanisms include magnetic mirroring of incoming solar wind particles and mechanisms involving transmission of particles through the shock. Secondly, the kinematics of observable electrons streaming away from a curved shock with an initial parallel velocity and a downstream perpendicular velocity component due to the motional electric field must be determined. This is the context in which the observations and their explanations will be reviewed.

The shock parameters are obtained from upstream measurements of the solar wind and magnetic field, and the input particles are drawn from convected Maxwellians, representing solar wind particles. Good agreement between downstream spectral measurements and the simulation predictions are obtained by allowing the parameter lambda/r(g), the ratio of the mean-free scattering length to the ionic gyroradius, to vary in an optimization of the fit to the data.

The current extension of this work to compare simulation predictions with particle spectra at oblique interplanetary shocks has required the inclusion of significant cross-field diffusion (strong scattering) in the simulation technique, since oblique shocks are intrinsically inefficient in the limit of weak scattering. In this paper, we present results from the method we have developed for the inclusion of cross-field diffusion in our simulations, namely model predictions of particle spectra downstream of oblique subluminal shocks. While the high-energy spectral index is independent of the shock obliquity and the strength of the scattering, the latter is observed to profoundly influence the efficiency of injection of cosmic rays into the acceleration process.

The surface of Mars is highly oxidized, as evidenced by its red color, but the connection to life is less apparent. Two possibilities can be considered. First, the oxidant may be photochemically produced in the atmosphere. In this case the fundamental source of O-2 is the loss of H-2 to space and the oxidant produced is H2O2. This oxidant would accumulate on the surface and thereby destroy any organic material and other reductants to some depth. Recent models suggest that diffusion limits this depth to a few meters. An alternative source of oxygen is biological oxygen production followed by sequestration of organic material in sediments-as on the Earth. In this case, the net oxidation of the surface was determined billions of years ago when Mars was a more habitable planet and oxidative conditions could persist to great depths, over 100 m. Below this must be a compensating layer of biogenic organic material. Insight into the nature of past sources of oxidation on Mars will require searching for organics in the Martian subsurface and sediments. C1 NASA, AMES RES CTR, MOFFETT FIELD, CA 94035 USA.

The collection includes remote (mostly ground based) observations as well as measurements made in situ by the spacecraft that encountered the comet in March 1986. Only the set of 24 CD-ROMs that comprise the remote observations which were released in 1993 are discussed. The observations of Halley are collected chronologically on 23 CD-ROMs; an added volume (24) includes data from comets Giacobini-Zinner and Crommelin. The data were collected into nine disciplines of astronomical observations: Astrometry, Infrared Studies, Large-Scale Phenomena, Near Nucleus Studies, Photometry and Polarimetry, Radio Studies, Spectroscopy and Spectrophotometry, Amateur Observations, and Meteor Studies. Observations cover the time period from December 1981 through April 1989. There were over 60,000 individual observations recorded. The design and production of this collection is discussed as well as statistics giving the full scope of the data. Initially, the CD-ROMs are being distributed to all of the contributors who requested them from the IHW and to major astronomical facilities around the world. Additional copies of the set of 24 CD-ROMs can be obtained through the NASA Planetary Data System Small Bodies Node at the University of Maryland and/or NASA's National Space Sciences Data Center.

Thin films of the phenylphosphine oxide-containing polymers were exposed to a radiofrequency-generated oxygen plasma under vacuum along with Kapton(R) HN and polymers of similar chemical structure that did not contain the phenylphosphine oxide group. The stability of the materials to the oxygen plasma was assessed by monitoring the weight loss of the films as a function of exposure time. After 23 h oxygen plasma exposure the phenylphosphine oxide-containing polymers exhibited weight-loss rates that were 40 to 145 (1-2 orders of magnitude) times slower than that of Kapton(R) HN, whereas polymers of similar chemical structure that did not contain the phenylphosphine oxide group exhibited weight-loss rates about 1-3 times faster than that of Kapton(R) HN. The changes in surface chemistry of the exposed films were subsequently examined using X-ray photoelectron spectroscopy. The phosphorus and oxygen near the surface exhibited increases in relative concentration and the photopeaks shifted towards higher binding energies. These changes are indicative of the formation of phosphate-type species. In addition, limiting oxygen indices were calculated from char yields at 850 degrees C in nitrogen utilizing a known method. For the most part, the incorporation of the phenylphosphine oxide group did not substantially increase the limiting oxygen indices of these experimental polymers.

In one approach, we employ sum-overstates calculations at the INDO-SDCI level on (CH3)(2)N-(CH=CH)(4)-CHO, including an external, static, homogeneous electric field that unes the degree of ground-state polarization and BLA. In the second approach, we use a simple semiclassical model, wherein the mixing of valence bond (VB) and charge-transfer (CT) states along a BLA coordinate is treated. Qualitatively, the two approaches give very similar structure-property trends, that are consistent with experimental hyperpolarizability data on donor-acceptor polyenes. The agreement of the calculated trends reflects the importance of VB-CT energetics in determining them. C1 CALTECH,BECKMAN INST,PASADENA,CA 91125.

The ion-figuring process involves bombarding a component with a stable beam of accelerated particles, which selectively removes material from the surface. The specific figure corrections are achieved by rastering the fixed-current beam across the workpiece at varying velocities. Unlike conventional methods, ion figuring is a noncontact technique that avoids such problems inherent in traditional fabrication processes as edge roil-off effects, tool wear, and force loading of the work piece. Other researchers have demonstrated that ion beam figuring is effective for correcting of large optical components. This work is directed toward the development of the precision ion-machining system (PIMS) at NASA's Marshall Space Flight Center (MSFC). This system is designed for processing small (congruent to 10 cm diameter) optical components. The ion-figuring process involves obtaining an interferometric error map of the surface, choosing a raster pattern for the beam, and determining the velocities along that path. Because the material removed is the convolution of the fixed ion beam removal and the rastering velocity as a function of position, determining the appropriate velocities from the desired removal map and the known ion beam profile is a deconvolution process. A unique method of performing this deconvolution was developed for the project, which is also applicable to other mathematically similar processes, including computer-controlled polishing. This paper presents the deconvolution algorithm, a comparison of this technique with other methods, and a simulation analysis. Future research will implement this procedure at MSFC.

The effects of geometric scaling of specimen size, ply-level and sublaminate-level scaling of the stacking sequence, and trigger mechanism on the energy absorption capability in edgewise compression were evaluated. Scaling method and matrix material were found to influence the preferred crushing mode and energy absorption efficiency of the composite plates. Energy absorption and crushing modes where found to be similar to that of composite tubes. C1 NASA,LANGLEY RES CTR,USA,VEHICLES STRUCT DIRECTORATE,HAMPTON,VA 23665.

We identify this problem as the furnace temperature control problem. The thermal boundary conditions, in turn, dictate the interface shape between the solid and the liquid region of the material. Determination of the boundary conditions for a given desired interface shape is considered as the material temperature control problem in this paper. We outline the current efforts for the solution of the furnace temperature control and the material temperature control problems. We restrict our review to Bridgman growth control techniques.

One of the major advantages of ASCA's telescopes is the first time ever use of X-ray imaging over a broad energy band and high throughput for conducting astronomical spectroscopy. Nested thin foil reflectors make possible a large effective area up to 10 keV, even under the tight weight restriction of the ASCA spacecraft. The expected characteristics of the ASCA mirrors are summarized based on ray tracings and pre-flight calibrations. The total effective area of four telescopes at 1 and 7 keV are approximately 1200 and 600 cm2, respectively. The image size (half power diameter : HPD) is about 3'. The field of view is 24' and 16' FWHM for 1 and 7 keV, respectively. Observations of several X-ray sources from space during the performance verification phase have confirmed those performances as well as the alignment of the optical systems.

Before 1990, the long-term ephemeris of Cyg X-3 required the introduction of a second time derivative, P, of order -(1.27 +/- 0.19) x 10(-10) yr(-1) This value indicates that the first time derivative, P, changes from a positive to a negative value around 1986. However, the new ASCA data points presented here do not confirm this large P variation and indicate a significantly smaller P of -(8.13 +/- 1.15) x 10(-11) yr(-1) and a global period change of P/P = (1.17+/-0.44) x 10(-6) yr(-1). The derived P can be explained by a large mass-loss rate of 0.58 x 10(-6) M(T) yr(-1), where M(T) is the total mass of the Cyg X-3 system. This value is consistent with the expected mass-loss rate of the Wolf-Rayet star of about 10(-6)M(.) yr(-1). The existence of a red-noise type fluctuation is also described.

About 250 ks of deep survey data has been collected from the performance verification phase of ASCA. About 110 ks of dark-earth data are used to assess the internal background. A single power-law describes the X-ray background very well in the 1 to 10 keV with no evidence for a steepening in the 1 to 3 keV range. At 1 keV, the intensity of the X-ray background is 9.6 keV s(-1) cm(-2) sr-l keV(-1). Our data clearly show an excess above the extrapolation of the single power law model below 1 keV. At least part of this excess can be accounted for with a thermal component as there is evidence for O VII and O VIII emission. C1 UNIV CAMBRIDGE,INST ASTRON,CAMBRIDGE CB3 0HA,ENGLAND.

Such quantities are useful for handling effects not seen after low-LET radiation. Since appropriate cross-section functions for cancer induction for each particle species are not yet available, the conventional quality factor is used as an approximation to obtain numerical results for risks of excess cancer mortality. Risks are obtained for seven of the most radiosensitive organs as determined by the ICRP [stomach, colon, lung, bone marrow (BFO), bladder, esophagus and breast], beneath 10 g/cm(2) aluminum shielding at solar minimum. Spectra are obtained for excess relative risk for each cancer per LET interval by calculating the average fluence-LET spectrum for the organ and converting to risk by multiplying by a factor proportional to R(gamma) L Q(L) before integrating over L, the unrestricted LET. Here R(gamma) is the risk coefficient for low-LET radiation (excess relative mortality per Sv) for the particular organ in question. The total risks of excess cancer mortality obtained are 1.3 and 1.1% to female and male crew, respectively, for a 1-year exposure at solar minimum. Uncertainties in these values are estimated to range between factors of 4 and 15 and are dominated by the biological uncertainties in the risk coefficients for low-LET radiation and in the LET (or energy) dependence of the risk cross sections (as approximated by the quality factor). The direct substitution of appropriate risk cross sections will eventually circumvent entirely the need to calculate, measure or use absorbed dose, equivalent dose and quality factor for such a high-energy charged-particle environment.

The advent of the International Space Station Alpha and the renewed interest in human exploration and development of space bring radiation issues once again to the forefront. Opportunities exist for ground-based research leading to well-defined flight experiments that require the unique Facilities or attributes of a space station and for experiments on the US Shuttle that can be implemented without the use of major mission resources (''Small Payload Experiments''). Facilities to test and validate experimental equipment and to simulate different levels of gravitational acceleration are available for use by experiments. In addition, the NASA Biospecimen Sharing Program offers the scientific community access to tissues from organisms that have flown in space. Taking advantage of these opportunities requires imaginative approaches to radiation research, in order to develop critical experiments that can be validated in space and contribute to the science on which risk prediction must be based.

In addition to the still unresolved issues relating to current commercial operations (12-16 km), the higher dose rates associated with the higher operating altitudes makes it imperative that the uncertainties in the atmospheric radiation environment and the associated health risks be re-examined. Atmospheric radiation associated with the galactic cosmic rays forms a background level which may, under some circumstances, exceed newly recommended allowable exposure limits proposed on the basis of recent evaluations of the A-bomb survivor data (due to increased risk coefficients). These larger risk coefficients, within the context of the methodology for estimating exposure limits,are resulting in exceedingly low estimated allowable exposure limits which may impact even present day flight operations and was the reason for the CEC workshop in Luxembourg (1990). At higher operating altitudes, solar particle events can produce exposures many orders of magnitude above background levels and pose significant health risks to the most sensitive individuals (such as during pregnancy). In this case the appropriate quality factors are undefined, and some evidence exists which indicates that the quality Factor for stochastic effects is a substantial underestimate.

To obtain a better understanding of the underlying wave-particle mechanisms, we have studied energetic electron data from the Burst and Transient Source Experiment (BATSE) on NASA's Compton Gamma Ray Observatory (GRO) satellite. Wave-particle interactions are detected when the satellite traverses a cloud of energetic electrons which have been scattered into quasi-trapped trajectories by VLF waves. The previously reported seasonal variation in the frequency of occurrence of cyclotron resonance interaction is confirmed with the continuous coverage provided by GRO. These data also provide the first detailed measurements of the frequency of occurrence of the quasi-trapped electron fluxes as a function of local time at the transmitter. The variations are more complex than just a day-night effect, and the precipitation is most often seen in the predawn hours. As with the seasonal changes, the local time variations are governed by the transmission of VLF waves through the ionosphere.

Due to the low intensity of solar radiation, solar batteries are not adequate for this mission and radioisotope thermoelectric generators (RTGs) are utilized to supply the electric power to the spacecraft systems. The presence of a radioactive material on board and the consequences of a potential accident during the launch and near-earth phases of the mission require a scrupulous process of risk assessment to be executed before launch approval is granted at the highest level. For this purpose, the probabilistic risk assessment (PRA) approach has been chosen and applied throughout the analysis process. This paper describes the Cassini PRA methodology and presents the steps which have been accordingly executed to develop potential launch accident scenarios and their quantification.

Using such a model for real time monitoring and diagnosis of dynamic systems may require frequent reconfiguration and solution of the model. As such, an efficient algorithm must be used for model solution. This paper describes a new algorithm, called SourceDoubls, which efficiently solves for singletons and doubletons of a digraph reliability model. Compared with previous methods, the SourceDoubls algorithm provides up to a second order of magnitude reduction in the amount of time required to solve large digraph models. This significant increase in model solution speed allows complex digraphs containing thousands of nodes to be used as knowledge bases for real time automated monitoring and diagnosis applications. Currently an application to provide monitoring and diagnosis of the Space Station Freedom Data Management System (DMS) is under development at NASA/Ames Research Center (ARC) and NASA/Johnson Space Center (JSC). The Control Center Complex (CCC) at JSC is planning to install this application in a console position in the CCC to assist mission controllers responsible for the DMS. This paper contains an overview of this system and provides details of how it will use digraph models processed by the SourceDoubls algorithm to accomplish its task.

The goal was to assess the progress of the East decade in the areas of modeling, satellite data algorithm development, and field experiments. This article includes: 1. A review of the state and direction of biosphere-atmosphere model development and an assessment of the data needs of the models. Models covering a large range of timescales were considered: energy-water-carbon (seconds to seasons); carbon cycles and biogeochemistry (days to years); and ecological structure and function (years to millennia). 2. A reference to current satellite data algorithms and other global data sources. The areas covered in the workshop were: near-surface meteorology, surface radiation budget, precipitation, runoff; snow and ice, soils and soil moisture, and land cover type and land cover attributes. These are discussed in detail in other articles in this issue. 3. A review of completed and planned major field experiments. The major experiments of the last decade are summarized and the lessons noted, The participating scientists agreed on the need to rapidly assemble and circulate global data sets of variables and parameters required to initialize, force, and validate the global biosphere-atmosphere models. A prioritized list of data sets required to meet this need is set out and discussed. Lastly, initiatives taken by ISLSCP to satisfy these requirements are reviewed: Initiative I: Immediate Generation of High Priority Global Data Sets Some essential global data sets are to be put together within 2 years and released to the community by mid-1994. These data sets will be mapped to a common spatial resolution (1 degrees x 1 degrees) and will cover the period 1987-1988. 1. Vegetation: Global sets of vegetation-related parameters are to be generated with a monthly time resolution. Available AVHRR data sets are to be I used as the basis for this effort, and algorithms will be applied to calculate fields of cover type, phenology, FPAR, and leaf area index. These fields can then in turn be used to infer other surface pa rameters such as roughness, albedo, biomass, etc. 2. Hydrometeorology: Global meteorological fields retrieved from numerical reanalysis will be manipulated to provide near-surface forcing data sets for temperature, humidity, windspeed, etc. Observations of precipitation, runoff, and snow cover are to be worked up into easily accessible forms. 3. Radiation Budget: A closer interface with the International Satellite Cloud Climatology Project (ISCCP) and related projects will be pursued to obtain surface radiation budget components at higher spatial resolutions, as well as fields of incident PAR. 4. Soils: A small project was set in place with the goal of providing a useful soil type and properties data set for use by global modelers. Initiative II: Improved, Follow-on Data Sets The data sets specified in Initiative I are to be generated within a e-year period. However, it is clear that great improvements could be made over this first data release which must rely on pre-existing data sets and robust, available algorithms. Work was started to scope out what needs to be done to produce improved versions of all the Initiative I data sets within 5 years, by mid-1997. Initiative III: Improved Communications within the Land Science Community Future discussions within ISLSCP and between ISLSCP and other bodies will focus on the need to coordinate different research thrusts within the land science community, particularly the modeling, algorithm and field experiment work.

Although not yet a demonstrated global capability, the most feasible method for obtaining these parameters and updating them periodically, is satellite remote sensing. In this paper we will summarize our understanding of the desired land surface parameters, including soil moisture, and provide an assessment of the state of the art of surface state remote sensing algorithms to infer those parameters on a global basis. First, we will consider a) modeling requirements for land cover parameters, including vegetation community composition and biophysical parameters, for example, leaf area index (LAI), biomass density, fraction of photosynthetically active radiation (Fpar) absorbed by the vegetated land surface, and b) modeling requirements for soil moisture. We will then review the status of remote sensing algorithms for obtaining these parameters and examine a number of issues involved in the global implementation and testing of these algorithms. Finally, we will look at future needs to make global mapping of land cover parameters a reality. C1 UNIV MARYLAND, DEPT GEORGETOWN, COLLEGE PK, MD USA.

Modeling of top-of-the-atmosphere and top-of-the-canopy radiance field is developed as boundary value problems in radiative transfer. The parameterization of the constituent functions with simple models and/or empirical data is outlined together with numerical solution methods and examples of results of model validation. Caveats in the assignment of signal characteristics to surface properties are itemized and discussed with example results. Algorithms to estimate surface properties from remote observations are classified as spectral vegetation indices, model inversion, expert systems, neural networks, and genetic algorithms. Their applicability is also discussed. C1 UNIV CLERMONT FERRAND,METEOROL PHYS LAB,CLERMONT FERRAND,FRANCE. UNIV COLORADO,DEPT AEROSP ENGN STUDIES,BOULDER,CO.

However, the soil moisture response fi-om them is coupled to vegetation and surface roughness effects, and therefore the interaction among all three needs to be understood. This paper reviews the progress made in the measurement of soil moisture and the factors such as vegetation and surface roughness that affect these measurements. The active techniques, particularly those employing synthetic aperture radar (SAR), provide opportunities for soil moisture studies over a large area, and various aircraft and space missions have been carried out to achieve them. Still, there are unresolved questions about deriving soil moisture from these missions, and research is underway to develop algorithms so that soil moisture information can be obtained on a focal as well as a global basis.

It was intended to improve our understanding of the interaction between the Sahel and the general atmospheric circulation, both at present and in the future, providing a base line for studies of climate change. It was carried out in a 1 degrees X 1 degrees area of west Niger over a 3-4 year period with an 8-week intensive observation period from August to October 1992. HAPEX-Sahel was funded by a wide range of agencies in seven participating countries. Over 170 scientists visited and worked in the field. An interdisciplinary approach was adopted with contributed studies in hydrology and soil moisture surface fluxes and vegetation, remote sensing science, and meteorology and mesoscale modeling Detailed field measurements were concentrated at 3 ''supersites'' and 3 ancillary sites. Four aircraft were used for remote sensing and flux measurement. Observations from space were acquired from nine sensors on seven different satellite platforms. Conditions in 1992 turned out to be average far the last decade with good gradients of precipitation and a variety of vegetation productivities between the study sites. An information system has been established to provide a data base to disseminate the measurements. An active program of meetings, workshops, and interdisciplinary studies is now in progress.

Ultrasonic velocity, attenuation coefficient, and reflection coefficient images were obtained simultaneously over a broad band of frequencies (e.g., 30 to 110 MHz) by using spectroscopic analysis. Liquid and membrane (dry) coupling techniques and longitudinal and shear-wave energies were used. The major results include the following: ultrasonic velocity (longitudinal and shear wave) images revealed and correlated with the extent of average through-thickness pore fraction variations in the silicon nitride disks. Attenuation coefficient images revealed pore fraction nonuniformity due to the scattering that occurred at boundaries between regions of high and low pore fraction. Velocity and attenuation coefficient images were each nearly identical for machined and polished disks, making the method readily applicable to machined materials. Velocity images were similar for wet and membrane coupling. Maps of apparent Poisson's ratio constructed from longitudinal and shear-wave velocities quantified Poisson's ratio variations across a silicon nitride disk. Thermography images of a disk indicated transient thermal behavior variations that correlated with observed variations in pore fraction and velocity and attenuation coefficients.

Various methods of estimating latent heat flux (or evaporation) using remotely sensed data are reviewed. A method is proposed for estimating unstressed transpiration from meteorologic satellite data. Considering theory and field observations it is proposed that under many situations unstressed transpiration can expressed as a product of potential evaporation and fractional vegetation cover. Approaches for estimating potential evaporation and fractional cover from meteorological satellite observations (e.g. by METEOSAT and AVHRR) are discussed.

The Program has broadened its support for the ballooning community through the enhancement of current capabilities and the development of new capabilities. The long duration balloon project has continued to mature; the Antarctic long duration capability has been declared operational, and the successful conclusion of the development effort will be realized in the very near future with the completion of mid-latitude long duration capability. Recent years have seen increases in the number and complexity of remote campaigns requirements. New ground station support equipment has been implemented, the new mobile launch vehicle has became operational, slid new systems have been developed to meet the increasing demands. The comprehensive research and development (R & D) effort has continued with advances being made across the spectrum of balloon related disciplines. An overview of the various aspects of the NASA Balloon Program, their progress, status, and future plans will be presented.

The objectives are to develop the understanding of balloon system performance, limitations, and failure mechanisms. The program consists of five major technical areas: structures, performance and analysis, materials, chemistry and processing, and quality control. Research activities are being conducted at NASA/Goddard Space Flight Center (GSFC)/Wallops Flight Facility (WFF), other NASA centers and government facilities, universities, and the private sector. Significant technical advances have been made in the structural design and analysis of balloons, vertical flight performance modeling, materials characterization, materials development and processing, and the development of automated flight control hardware and software. This has resulted in new balloon designs with increased capabilities with improved flight control. The recent findings, new capabilities, and plans for the NASA Balloon R & D Program will be presented.

Since, inflation has had almost as much impact on cosmology as the big-bang model itself. However, unlike the big-bang model, it has little observational support. Hopefully, that situation is about to change as a variety and abundance of data begin to test inflation in a significant way. The observations that are putting inflation to test involve the formation of structure in the Universe, especially measurements of the anisotropy of the cosmic background radiation. The cold dark matter models of structure formation motivated by inflation are holding up well as the observational tests become sharper. In the next decade inflation will be tested even more significantly, with more precise measurements of CBR anisotropy, the mean density of the Universe, the Hubble constant, and the distribution of matter, as well as sensitive searches for the nonbaryonic dark matter predicted to exist by inflation. As an optimist I believe that we may be well on our way to a standard cosmology that includes inflation and extends back to around 10(-32) sec, providing an important window on the earliest moments and fundamental physics.

Their spectra are usually dominated by lines from highly ionized metals (usually He- and H-like ions). In young remnants the metal abundances are enriched by ejecta, resulting in very strong lines. ASCA's broad band allows simultaneous measurements of plasma diagnostics from oxygen to iron. Galactic remnants can be spatially resolved using ASCA's imaging capabilities, facilitating measurements of plasma properties as a function of distance from the shock and spectral mapping of regions of particular interest. Finally, it is possible to combine ASCA's spectral and spatial resolution to produce the first X-ray images of SNR's in the light of a particular element, or in the line-free continuum, thereby allowing searches for stratification and clumping which might reveal important clues about the nature of the progenitor star and the explosion mechanism. Below we present via examples three fundamental new insights on SNR's provided by ASCA. RP NASA, GODDARD SPACE FLIGHT CTR, GREENBELT, MD 20771 USA.

EGRET measures the high energy gamma-rays with its large NaI scintillator (1 to 200 MeV) and its spark chamber (30 MeV to 30 GeV). The spark chamber also measures lime and arrival directions of individual photons cowing locations for the energetic bursts to be determined. Since the Compton Gamma Ray Observatory launch in 1991, EGRET has observed five bursts in the spark chamber with several having gamma-ray energies grater than 1 GeV. The recording breaking burst, GRB940217, had gamma-rays up to 18 GeV and lasted over 5000 seconds. The results for the energetic bursts are presented. The high energies observed from these gamma-ray bursts set constraints for the burst distances. C1 MAX PLANCK INST EXTRATERR PHYS,D-85740 GARCHING,GERMANY. STANFORD UNIV,STANFORD,CA 94305.

Investigating the kinetics of these reactions expands our understanding of nutrient release processes. Research was conducted to model transport kinetics of nutrient release in Cp-PR systems, The objectives were to identify empirical models that best describe NH4, K, and P release and define diffusion-controlling processes. Materials included a Texas clinoptilolite (Cp) and North Carolina phosphate rock (PR), A continuous-flow thin-disk technique was used, Models evaluated included zero order, first order, second order, parabolic diffusion, simplified Elovich, Elovich, and power function, The power-function, Elovich, and parabolic-diffusion models adequately described NH4, K, and P release, The power-function model was preferred because of its simplicity. Models indicated nutrient release was diffusion controlled. Primary transport processes controlling nutrient release for the time span observed were probably the result of a combination of several interacting transport mechanisms, C1 TEXAS A&M UNIV,DEPT SOIL & CROP SCI,COLLEGE STN,TX 77840.

The observed X-ray images are compared with force-free magnetic fields with different values of alpha, extrapolated from the MSFC photospheric magnetogram observed at the same time. The results show that the magnetic field of the active region is not potential. Different groups of loops are characterized by different values of alpha. Bright loops correspond to field with large alpha, indicating twisting of the loop. However, there is no obvious correlation between the brightness of individual loops with the amount of twist. Further investigation of the magnetic state of the loop structure requires accurate nonlinear force-free calculations. C1 UNIV ALABAMA,HUNTSVILLE,AL 35899.

The high-latitude phenomena observed to date have been strongly influenced by the near-minimum solar activity conditions encountered during this phase of the mission. In late April 1993, when Ulysses was at similar to 29 degrees S heliographic latitude, the recurrent high speed solar wind stream that had been observed at the location of the spacecraft for 11 consecutive solar rotations underwent a dramatic change. The wind speed in the valleys between successive peaks increased in a single step from similar to 420 km s(-1) to similar to 560 km s(-1). This change in solar wind flow was accompanied by the disappearance at the spacecraft of the magnetic sector structure that had been observed until then. Both these findings are consistent with Ulysses having climbed beyond the latitude of the coronal streamer belt in which is embedded the heliospheric current sheet (HCS), In its subsequent poleward journey, no further evidence for an encounter with the HCS has been seen at Ulysses. Other phenomena observed include the evolution with latitude of corotating interaction regions (CIRs) and their influence on the acceleration of energetic particles, and the characteristics of the solar wind flows emanating from the south polar coronal hole. In this paper, we present details of the above observations. Finally, while the polar passes of the prime mission will take place near solar minimum, an extended mission will bring Ulysses back over the poles near the maximum of the next cycle. A summary of scientific goals for Ulysses at solar maximum is given. C1 CALTECH,JET PROP LAB,PASADENA,CA 91109.

The available energy release under a solar flare controlled by the helicity conservation is shown to be defined by the magnetic structure of the associated prominence. The approach throws light on some solar flare enigmas: the role of the associated prominences; the discontinuation of the reconnection of magnetic lines long before the complete reconnection of participated fields occurs; the existence of quiet prominences which, in spite of their usual optical appearance, do not initiate any flare events; the small energy release under a solar flare in comparison with the stockpile of magnetic energy in surrounding fields. The predicted scale of the energy release is in a fair agreement with observations. C1 NATL OPT ASTRON OBSERV,NASA,GODDARD SPACE FLIGHT CTR,HUGHES STX,SW STN,TUCSON,AZ 85726.

Over 400 payload-days of data have been made during a record setting experiment called ELBBO (Extended Life Balloon Borne Observatories). This experiment resulted in 4 flights aloft simultaneously for over 2 months including one flight which lasted over 4 months. Electrodynamical coupling between the atmosphere and ionosphere is studied using the measured electric fields, and a simple empirical model of the stratospheric conductivity. Altitude profiles of conductivity have been obtained from several superpressure balloon flights using the large end-of-flight altitude swings on the last few days of each flight (as the balloon begins to loose superpressure). Coupling between the fields and atmospheric inertial waves has been observed. Effects and dynamics of the global circuit suggest that standard models are missing significant phenomena. Large scale ionospheric convection activity has been studied from the polar cap to the middle latitudes. Cusp latitude fields have been continuously measured for many days in a row.

Nearly 2500 hours of data have been collected since 1990. The radar can detect debris sizes as small or smaller than 1-cm diameter at 500 km altitude. Tn general, the measured debris population is smaller than predicted for altitudes below 850 km and larger than predicted for altitudes between 850 and 1000 km. A partial explanation is that the low altitude debris population decreased during the high part of the last solar cycle but has not increased as predicted during the current low solar activity.

For objects in low earth orbit (LEO), the observation time is limited to conditions of astronomical twilight, typically an hour or two after sunset and before dawn. In addition, objects in LEO have a relatively high angular velocity, and pass through the field of view of the telescope rapidly. This limits the integration time possible for LEO objects. Radars have the advantage over optical methods for LEO measurements, since large amounts of microwave power can be used to get a high signal return, and radar observations can be done continuously, not constrained by weather and position of the sun. Even so, useful information about the debris population in low earth orbit can be obtained using optical techniques. Telescopes have been used to obtain statistical measures of population of LEO debris at sizes greater than about 10 cm since 1984. Optical methods come into their own for measurements of satellites at extreme altitudes, such as those near geosynchronous earth orbit (GEO). First, the observation time can extend through all or most of the night. Also, the signal from sunlight reflected by the satellite falls off only as the square of the altitude of the satellite, while the signal from a radar beam reflected from a satellite falls off as the fourth power of the altitude. As a consequence, optical telescopes of modest size can outperform radars for objects at GEO altitudes. A limited number of optical measurements of debris near the geosynchronous are and in geotransfer orbits have been done. These have shown that there does exist a small debris population in these orbits, but much more work is needed to define this debris population.

However, it was realized from the beginning that the most efficient use of the satellite would be to characterize impact features from the entire surface of LDEF. With this in mind, particular interest has focused on common materials facing in all 26 LDEF facing directions; among the most important of these materials has been the LDEF frame and tray clamps. Therefore, in an effort to better understand the nature and flux of particulates in LEO, and their effects on spacecraft hardware, we are locating all impact features on LDEF frame member intercostals and tray clamps, down to 40 mu m in diameter, analyzing the bulk major-element composition of impactor residues when present. We also describe current efforts to characterize impactor residues recovered from the impact craters, and we have found that a low, but significant, fraction of these residues have survived in a largely unmelted state. These residues can be characterized sufficiently to permit resolution of the impactor origin. We have concentrated on the residue from chondritic interplanetary dust particles (micrometeoroids), as these represent the harshest test of our analytical capabilities. We describe the Meteoroid and Debris Database, into which we have placed all pertinent LDEF data, as well as similar results from inspection of the Solar Maximum and Palapa Satellites. Finally, we describe the contents of the Final Report of the LDEF Meteoroid and Debris Special Investigation Group, which is currently being prepared. C1 LOCKHEED ENGN & SCI CO,HOUSTON,TX 77058.

Historical radar cross sections (RCSs) were analyzed to determine their means and standard deviations. A laboratory-derived statistical estimator of characteristic size is discussed and applied to the RCS statistics to yield characteristic sizes of orbital debris. These area-to-mass ratios and characteristic sizes were combined to produce statistical estimates of object mass. These are categorized by fragmentation progenitor, such as the Delta second stage rockets, and debris cloud membership. Distributions in area-to-mass and estimated size and mass are examined for structure and compared to current models. C1 NASA,LYNDON B JOHNSON SPACE CTR,HOUSTON,TX 77058.

Access to and operations in space require a large expenditure of energy. Current objects placed into orbit contain a large amount of residual energy. This energy can include stored energy in the form of unburned propellant, batteries, or pressurized containers, but always includes an even larger amount of energy in the form of kinetic energy. The importance of this residual energy is that it is the energy source for re-distributing the kinetic energy into various debris sizes. The only natural ''sink'' for the residual energy is atmospheric drag, which is more fundamentally expressed as an energy loss rate. By approaching orbital debris as an energy management rather than object management problem, some of the fundamental issues concerning orbital debris become more obvious. For example, the amount of kinetic energy in orbit far exceeds the amount of stored energy; consequently any long-term debris management strategy must consider managing kinetic energy. These principles can be applied to both low Earth orbit and Geosynchronous orbit and illustrate the need for different strategies in these two regions.

This handbook has been discussed in other papers/1,2/. In the last 8 months the handbook has been subject to two reviews within NASA. In December, 1993, comments were received from a general review of the handbook and guidelines. The document was modified and sent out for detailed technical review in June, 1994. In this paper the concerns raised during the review process will be discussed and the current form of the handbook guidelines and support documentation will described.

These differences result from the differences in the abundances of metals as determined from high dispersion spectra. Presumably, these abundance differences reflect differences in age. The high-velocity carbon stars share the molecular peculiarities of the high-velocity oxygen giants but, because of the greater strength of the bands of carbon-containing molecules, exhibit them to a greater degree.

The model shows how several neuropsychological theories of frontal lobe function can be combined into a single computer model. The model also extends those component theories by focusing on information processing details that glue the pieces together. This work is motivated by the point that neuropsychology and AI describe complementary parts of a model for autonomous action. Neuropsychological models provide descriptions of how planning and reaction must be integrated for human autonomy, but the planning component is poorly understood and many information processing details have not been flushed out. In contrast, AI provides implementations of independent planning and reaction modules, but their integration is poorly understood. A computer model forces information processing issues to be addressed in detail. A computer model can also be tested more easily than models based on verbal descriptions because it produces behavior that can be compared directly with clinically observed behavior. In contrast, verbal models must be interpreted subjectively to predict and test their behavior. NASA is interested in applying this model towards the development of autonomous instruments and spacecraft. Today's autonomous control technology is limited by executive function deficits that are similar to those found in frontal lobe patients. The control technology works well in preprogrammed situations, but it cannot reprogram itself to handle novel events. Our goal is to extend AI planning methods to simulate human executive functions in real-time closed-loop control applications. We also intend to use the model for a cognitive rehabilitation application. Earlier descriptions of the model can be found in references 1 and 2.

It employs a hierarchical structure of processing communication and memory name-space management resources to provide a scalable NUMA environment. Ensembles of 8 HP PA-RISC 7100 microprocessors employ an internal cross-bar switch and directory based cache coherence scheme to provide a tightly coupled SMP, Up to 16 processing ensembles are interconnected by a 4 ring network incorporating a full hardware implementation of the SCI protocol for a full system configuration of 128 processors. This paper presents the findings of a set of empirical studies using both synthetic test codes and full applications for the Earth and space sciences to characterize the performance properties of this new architecture. It is shown that overhead and latencies of global primitive mechanisms, while low in absolute time, are significantly more costly than similar functions local to an individual processor ensemble.

The flow solver is based on a second-order projection method applied to a staggered finite-difference grid. The multigrid algorithms implemented in the elliptic kernel, which is needed by the Row solver, are V-cycle and full V-cycle schemes. A grid-partition strategy is used in the parallel implementations of both the flow solver and the multigrid elliptic ker-nel on all fine and coarse grids. Numerical experiments and parallel performance tests show the parallel solver package is numerically stable, physically robust and computationally efficient. Both the mul-tigrid elliptic kernel and the now solver scale very well to a large number of processors on the Intel Paragon and. the Gray T3D for computations with moderate granularity. The solver package has been carefully designed and ceded so that it can be easily adapted to solving a variety of interesting two and three-dimensional flow problems. Tile solver package is portable to parallel systems that support MPI, PVM and Intel NX for interprocessor communications. Copyright 1995 by the Association for Computing Machinery, Inc. (ACM).

The calculations show the bonding mechanism in the sulfides and oxides to be very similar. For the oxides, accurate experimental data anew the theoretical methods to be calibrated. The same level of theory is used to study the sulfides where there is far less experimental information. For ScO through MnO and CuO the coupled cluster singles and doubles technique including a perturbational estimate of the connected triple excitations [CCSD(T)] yields spectroscopic constants (r(c), omega(c), and D-o) in good agreement with experiment. The triple excitations are found to be very important in achieving this accuracy. For FeO to NiO, the self-consistent-field (SCF) approach yields pi. orbitals that are localized on the metal or oxygen. This appears to cause problems for the single reference techniques; this is discussed in detail for NiO. The complete-active-space SCF/internally contracted averaged coupled pair functional approach (CASSCF/ICACPF) works well for FeO to NiO. The calculation of accurate dipole moments is found to be very difficult. RP BAUSCHLICHER, CW (reprint author), NASA,AMES RES CTR,MOFFETT FIELD,CA 94035, USA.

ALGORITHMIC CONSIDERATIONS AND VALIDATION SO THEORETICAL AND COMPUTATIONAL FLUID DYNAMICS LA English DT Article ID CONVERGENCE; VELOCITY AB A highly accurate algorithm for the direct numerical simulation (DNS) of spatially evolving high-speed boundary-layer flows is described in detail and is carefully validated. To represent the evolution of instability waves faithfully, the fully explicit scheme relies on nondissipative high-order compact-difference and spectral collocation methods. Several physical, mathematical, and practical issues relevant to the simulation of high-speed transitional flows are discussed. In particular, careful attention is paid to the implementation of inflow, outflow, and far-field boundary conditions. Four validation cases are presented, in which comparisons are made between DNS results and results obtained from either compressible linear stability theory or from the parabolized stability equation (PSE) method, the latter of which is valid for nonparallel flows and moderately nonlinear disturbance amplitudes. The first three test cases consider the propagation of two-dimensional second-mode disturbances in Mach 4.5 flat-plate boundary-layer flows. The final test case considers the evolution of a pair of oblique. second-mode disturbances in a Mach 6.8 flow along a sharp cone. The agreement between the fundamentally different PSE and DNS approaches is remarkable for the test cases presented. C1 NASA,LANGLEY RES CTR,COMPUTAT SCI BRANCH,HAMPTON,VA 23681.

The 1st-order stimuli are moving sine gratings. The 2nd-order stimuli are fields of static visual texture, whose contrasts are modulated by moving sine gratings. Neither the spatial slant (orientation) nor the direction of motion of these 2nd-order (microbalanced) stimuli can be detected by a Fourier analysis; they are invisible to Reichardt and motion-energy detectors. Method. For these dynamic stimuli, when presented both centrally and in an annular window extending from 8 to 10 deg in eccentricity, we measured the highest spatial frequency for which discrimination between +/-45 deg texture slants and discrimination between opposite directions of motion were each possible. Results. For sufficiently low spatial frequencies, slant and direction can be discriminated in both central and peripheral vision, for both 1st- and for 2nd-order stimuli. For both 1st- and 2nd-order stimuli, at both retinal locations, slant discrimination is possible at higher spatial frequencies than direction discrimination, For both 1st- and 2nd-order stimuli, motion resolution decreases 2-3 times more rapidly with eccentricity than does texture resolution. Conclusions. (1) 1st- and 2nd-order motion scale similarly with eccentricity. (2) 1st- and 2nd-order texture scale similarly with eccentricity. (3) The central/peripheral resolution fall-off is 2-3 times greater for motion than for texture. RP NASA, AMES RES CTR, MAIL STOP 262-2, MOFFETT FIELD, CA 94035 USA.

These three stars share several common characteristics: (1) associated N- and He-enriched ring nebula, (2) spectral class WN5-8, and (3) spectral and photometric variability. Surveys of IUE spectra and IRAS images reveal a few additional candidates for such extended shells. Although positional coincidences cannot be excluded, possible origins of these extended shells include interstellar bubbles formed by stellar winds, non-conservative mass loss from binary systems, and supernova remnants. Current data suggest these three stars may be in a post X-ray binary stage, representing the second WR phase of massive binary star evolution. The discovery of extended shells of gas and dust possibly related to WR stars is important because the search for stars in the second WR phase, after the supernova of the primary, has been quite elusive. However, the observational evidence and available theoretical models for post-supernova massive binary star evolution and subsequent non-conservative mass transfer are not yet sufficient to firmly identify the origins of these extended shells.

The objective of these observations were: (1) to compare our results with previous observations made with the IPC (Moffat et al. 1982); (2) to explore the phase dependence of the X-ray variations; and (3) to look for evidence of the generation of X-rays from colliding winds in the system. ROSAT observed V444 Cygni with the PSPC five separate times, for a total integration time of about 20 ksec. Figure 1 shows the phase-binned light-curve along with archival IPC data. The observed X-ray variability can be modeled as a wind eclipse of an X-ray source by the WR wind. If most of the X-rays from the system are produced in a shock-heated region of wind interaction between the two stars, then the shocked gas has a large physical extent (r approximate to 140 R(WR)) if the observed variability is produced solely by the eclipse of the region by the WR wind. However, since the O star makes a significant contribution to the total X-ray flux from the system, the actual size of the shocked interaction region is probably much smaller.

The process of dust formation in the hydrogen-poor environments characteristic of WC winds is reviewed and compared to the chemical pathway to soot particle production in AGE stars. Emphasis is put on the formation of the dust precursors, and the physical conditions necessary to nucleate them in WC winds. In particular, it is concluded that dust formation around WC stars occurs in a dense, largely neutral, circumstellar disk. C1 NASA,AMES RES CTR,DIV SPACE SCI,MOFFETT FIELD,CA 94035.

These energetic particles can produce observable non-thermal radiation from the radio to gamma-rays. The important physical processes in such systems are very similar to those we have proposed for non-thermal emissions from single hot stars, which have shocks generated by instabilities in the radiatively driven stellar winds. This paper discusses the theory and observations of non-thermal radiation in the radio, X-ray, and gamma-ray regions from both single stars and massive binaries. Similarities and differences between the two types of systems are outlined. We discuss two important physical effects that apparently have been neglected in previous theoretical work on colliding wind binaries.

An exact solution of the Navier-Stokes equations is used as the background state to develop an asymptotic theory valid for thin annular layers, which leads to a novel nonlinear equation describing the spatio-temporal evolution of the interface. The evolution equation is an extension of the equation found for constant pressure gradients and generalizes the Kuramoto-Sivashinsky equation with dispersive effects found by Papageorgiou, Maldarelli and Rumschitzki, Phys. Fluids A 2(3), 340-352 (1990), to a similar system with time periodic coefficients. The distinct regimes of slow and moderate flow are considered and the corresponding evolution is derived. Certain solutions are described analytically in the neighborhood of the first bifurcation point by use of multiple scales asymptotics. Extensive numerical experiments, using dynamical systems ideas, are carried out in order to evaluate the effect of the oscillatory pressure gradient on the solutions in the presence of a constant pressure gradient.

Three independent pressure-strain models are considered along with a variety of explicit compressible corrections that account for dilatational dissipation and pressure-dilatation effects. The ability of the models to predict both time evolving fields and equilibrium states is systematically tested. Consistent with earlier studies, it is found that the addition of simple dilatational models allows for the prediction of the reduced growth rate of turbulent kinetic energy in compressible homogeneous shear flow. However, a closer examination of the equilibrium structural parameters uncovers a major problem. None of the models are able to predict the dramatic increase in the normal Reynolds stress anisotropies or the significant decrease in the Reynolds shear stress anisotropy that arise from compressible effects. The physical origin of this deficiency is attributed to the neglect of compressible terms in the modeling of the deviatoric part of the pressure-strain correlation.

The plasma has been spectroscopically diagnosed and the Al III soft x-ray spectrum predicted using a collisional radiative model incorporating the experimental plasma parameters and theoretical predictions for the properties of the autoionizing levels. The model includes collisional inner-shell ionization from Al II levels by fast electrons, inelastic collisions with cold Maxwellian electrons and radiative and autoionization decays. The comparison between the experimental and the predicted relative line intensities seems to confirm that most of the 2p(5)(3s3p P-3) Al III levels have large radiative branching ratios. This conclusion is supported also by a comparison between Al III and Mg II spectra obtained in similar excitation conditions. Several 2p(6)3p(2)P-2p(5)(3s3p(3)P)P-2,D-2 Al III transitions having radiative yields close to one and large gain cross sections, may be of interest for soft x-ray lasing.

Both spin-restricted, RCCSD(T), and spin-unrestricted, UCCSD(T), approaches are used. The UCCSD(T) bond length is much longer than the experimental value, while the RCCSD(T) bond length is shorter. This difference is due to the inability of the spin restricted Hartree-Fock reference to describe the antiferromagnetic coupling at larger r values. In contrast with the results obtained using density functional theory in conjunction with older functionals, the results obtained with recently developed functionals are in agreement with the UCCSD(T) results.

The main objectives of the study are to investigate (a) the temperature dependence of these reactions at a fixed H(2)0 partial pressure typical of the lower stratosphere (that is, by changing temperature at a constant water partial pressure, the H2SO4 content of the surfaces is also changed), (b) the relative importance or competition between reactions 1 and 2, and (c) the effect of HNO3 on the reaction probabilities due to the formation of a H2SO4/HNO3/H2O ternary system. The measurements show that all the reactions depend markedly on temperature at a fixed H2(O) partial pressure: they proceed efficiently at temperatures near 200 K and much slower at temperatures near 220 K. The reaction probability (gamma(1)) for ClONO2 hydrolysis approaches 0.01 at temperatures below 200 K, whereas the values for gamma(2) and gamma 3 are on the order of a few tenths at 200 K. Although detailed mechanisms for these reactions are still unknown, the present data indicate that the competition between ClONO2 hydrolysis and ClONO2 reaction with HCl may depend on temperature (or H2SO4 wt %): in the presence of gaseous HCl at stratospheric concentrations, reaction 2 is dominant at lower temperatures (<200 K), but reaction 1 becomes important at temperatures above 210 K. Furthermore, reaction probability measurements performed on the H2SO4/HNO3/ H2O ternary solutions do not exhibit noticeable deviation from those performed on the H2SO4/H2O binary system, suggesting little effect of HNO3 in sulfate aerosols on the ClONO2 and HOCl reactions with HCl. The results reveal that significant reductions in the chlorine-containing reservoir species (such as ClONO2 and HCl) can take place on stratospheric sulfate aerosols at high latitudes in winter and early spring, even at temperatures too warm for polar stratospheric clouds (PSCs) to form or in regions where nucleation of PSCs is sparse. This is particularly true under elevated sulfuric acid loading, such as that after the eruption of Mt. Pinatubo. Comparisons between our results and those presently available have also been made.

This storage system allows for the detection to be done at convenient times, as opposed to the nearly continuous monitoring that is required by other systems to preserve a sample time profile. The sample storage column is essentially a gas chromatography column, although its use is not the separation of sample components. The functions of the storage column are the selective isolation of the component of interest from the rest of the components present in the sample and the storage of this component as a function of time. Using octane as a test substance, the sample storage system was optimized with respect to such parameters as storage and readout temperature, now rate through the storage column, column efficiency and storage time. A 3-h sample profile was collected and stored at 30 degrees C for 20 h. The profile was then retrieved, essentially intact, in 5 min at 130 degrees C.

We self-consistently calculate the ionization balance and thermal balance in the medium along with the distribution of X-ray intensity with optical depth. In addition to absorption or scattering of the incident X-rays, we also compute the spectrum of X-rays emitted by the material, including lines, edges, and bremsstrahlung. The albedo of the medium depends primarily on the X-ray ionization parameter (ratio of incident flux to gas density, xi(x)), and secondarily on the UV flux generated by dissipation inside the disk; we locate the critical range of xi(x) over which the albedo increases from small to nearly unity. While the continuum reflection is very weak below 10 keV when xi(x), is small, significant fluxes are emitted in atomic lines and edges in this energy range. In the limit of large xi(x), the albedo below 10 keV increases, but reflection in this band is never ''gray'': some photoelectric absorption remains up to rather large values of xi(x), while at still higher values, inverse Compton scattering amplifies the soft X-ray flux. These features are sufficiently sharp that current and near-future X-ray experiments should permit diagnostic measures of xi(x). C1 JOHNS HOPKINS UNIV,DEPT PHYS & ASTRON,BALTIMORE,MD 21218.

The observations presented here augment an ongoing study of the organic component of the diffuse interstellar medium. These spectra contain a broad feature centered near 3300 cm(-1) (3.0 mu m) and/or a feature with a more complex profile near 2950 cm(-1) (3.4 um), the latter of which is attributed to saturated aliphatic hydrocarbons in interstellar grains and is the primary interest of this paper. As in our earlier work, the similarity of the absorption bands near 2950 cm(-1) (3.4 mu m) along different lines of sight and the correlation of these features with interstellar extinction reveal that the carrier of this band lies in the dust in the diffuse interstellar medium (DISM). At least 2.5% of the cosmic carbon in the local interstellar medium and 4% toward the Galactic center is tied up in the carrier of the 2950 cm(-1) (3.4 mu m) band. The spectral structure of the diffuse dust hydrocarbon C-H stretch absorption features is reasonably similar to UV photolyzed laboratory ice residues and is quite similar to the carbonaceous component of the Murchison meteorite. The similarity between the DISM and the meteoritic spectrum suggests that some of the interstellar material originally incorporated into the solar nebula may have survived relatively untouched in primitive solar system bodies. Comparisons of the DISM spectrum to hydrogenated amorphous carbon and quenched carbonaceous composite are also presented. The A(v)/tau ratio for the 2950 cm(-1) (3.4 mu m) feature is lower toward the Galactic center than toward sources in the local solar neighborhood (similar to 150 for the Galactic center sources vs. similar to 250 for the local ISM sources). A similar trend has been observed previously for silicates in the diffuse medium by Roche and Aitken, suggesting that (1) the silicate and carbonaceous materials in the DISM may be physically correlated and (2) there is either dust compositional variation in the galaxy or galactic variation in the grain population density distribution. We also note a possible absorption feature near 3050 cm(-1) (3.28 mu m), a wavelength position that is characteristic of polycyclic aromatic hydrocarbons (PAHs).

There are no published reports of previous emission from this 93.6 s X-ray pulsar. Recent optical results have suggested a Be star as the companion. A search of the EXOSAT archives shows that an ME observation centered on the star HD 88661 includes GRO J1008-57 within the held of view. The characteristics of the medium-energy detection including a hard spectrum and pulsed emission at 91.36 s (with chance probability of 3 x 10(-4)) indicates that EXOSAT detected GRO J1008-57 rather than the field star. The estimated flux is 2.4 x 10(-11) ergs cm(-2) s(-1) for a luminosity of 1.1 x 10(34)(D/2 kpc)(2) ergs s(-1). The X-ray spectrum is hard (photon index approximate to 1.2) and highly absorbed (N-H approximate to 0.7 x 10(22)). The detection of this transient suggests that there is a pulse shape dependence on luminosity, a spectral shape independent of luminosity, a large period derivative of P/P = 2.3 x 10(-3) yr(-1), and a dynamic range of at least 100 in L(x). We discuss GR J1008-57 data in the context of wind-accretion models for this new member of the Be class of X-ray binaries. C1 COMP SCI CORP,ASTRON PROGRAM,BALTIMORE,MD 21218.

Ice and amorphous nitric-acid/ice films were prepared by condensation of water and nitric acid vapors onto a wedged Al2O3 substrate. The real refractive indices of these films were determined from the optical interference of a reflected helium-neon laser during film growth. The indices of the amorphous films varied smoothly from n = 1.30 for ice to n = 1.49 for nitric acid, similar to observations in previous work. We were unable to obtain the refractive index of crystalline films during adsorption because of optical scattering caused by surface roughness. Therefore crystalline nitric acid hydrate films were prepared by annealing amorphous nitric-acid/ice films. Further heating caused desorption of the crystalline hydrate films. During desorption, the refractive indices for ice, NAM (nitric acid monohydrate), alpha- and beta-NAT (nitric acid trihydrate) films were measured using the optical interference technique. In agreement with earlier data, the real refractive indices for ice and NAM determined in desorption were n = 1.30 +/- 0.01 and n = 1.53 +/- 0.03, respectively. The real refractive indices for alpha- and beta-NAT were found to be n = 1.51 +/- 0.01 and n greater than or equal to 1.46, respectively. Out measurements also suggest that the shape of crystalline nitric acid particles may depend on whether they nucleate from the liquid or by vapor deposition. If confirmed by future studies, this observation may provide a means of distinguishing the nucleation mechanism of crystalline PSCs. C1 UNIV COLORADO, COOPERAT INST RES ENVIRONM SCI, BOULDER, CO USA.

Using a simple ozone depletion profile reflecting the observed decrease in ozone column abundance, Ramaswamy et al. (1992) showed that the negative radiative forcing that results from the ozone decrease between 1979 and 1990 approximately balanced the greenhouse climate forcing due to the chlorofluorocarbons emitted during the same period. Here, we extend the forcing analyses by calculating the equilibrium surface temperature response explicitly, using an updated version of the Atmospheric and Environmental Research two-dimensional radiative-dynamical seasonal model. The calculated steady state responses suggest that the surface cooling due to the ozone depletion in the lower stratosphere offsets about 30% of the surface warming due to greenhouse gases emitted during the same decade. The temperature offset is roughly a factor of 2 larger than the corresponding offset obtained from forcing intercomparisons. This result appears to be related to the climate feedback mechanisms operating in the model troposphere, most notably that associated with atmospheric meridional heat transport. Thus a comprehensive assessment of ozone change effects on the predicted greenhouse warming cannot be accomplished based on forcing evaluations alone. Our results also show that calculations adopting a seasonally and latitudinally dependent ozone depletion profile produce a negative forcing about 50% smaller than that calculated for the depletion profile used by Ramaswamy et al.

This requirement is made even more stringent when analyzing measurements of non-local thermodynamic equilibrium (non-LTE) emission from the terrestrial mesosphere and lower thermosphere. In principle, line-by-line calculations which explicitly account for the departure from thermodynamic equilibrium in both the source functions and the transmittances are necessary. In this paper we extend the emissivity growth approximation (EGA) technique developed for local thermodynamic equilibrium (LTE) conditions to the non-LTE environment. Computations of the non-LTE spectrally integrated limb radiance for the molecular oxygen dayglow (1.27 mu m and 762 nm), ozone and carbon dioxide in the 9- to 11-mu m spectral interval, carbon monoxide (4.6 mu m), nitric oxide (5.3 mu m), and the carbon dioxide bands (15 mu m) are presented. Using the non-LTE form of the EGA, the spectrally integrated limb emission is calculated for 35 tangent heights in the mesosphere and lower thermosphere (a total of 1200 atmospheric layers) with Line-by-line accuracy in similar to 0.35 s of CPU time on readily available desktop computer hardware, while the corresponding line-by-line calculations may require several minutes. The non-LTE EGA technique will allow kinetic temperature and minor constituent retrieval algorithms to readily include non-LTE effects limited only by the a priori knowledge of the departure from LTE in the observed bands.
