\title{
  Air Quality Dataset
}

\description{
  These datasets contain air quality measurements for training and testing purposes. They include various air pollutant concentrations and meteorological variables measured at different locations and times.
}

\usage{
data("air_quality_training")
data("air_quality_testing")
}

\format{
  Both datasets are data frames with 8760 rows and 12 variables:
  \describe{
    \item{Date}{Date and time of measurement (POSIXct format)}
    \item{PM2.5}{Particulate matter with diameter less than 2.5 micrometers (\eqn{\mu}{u}g/m^3)}
    \item{PM10}{Particulate matter with diameter less than 10 micrometers (\eqn{\mu}{u}g/m^3)}
    \item{SO2}{Sulfur dioxide concentration (\eqn{\mu}{u}g/m^3)}
    \item{NO2}{Nitrogen dioxide concentration (\eqn{\mu}{u}g/m^3)}
    \item{CO}{Carbon monoxide concentration (\eqn{\mu}{u}g/m^3)}
    \item{O3}{Ozone concentration (\eqn{\mu}{u}g/m^3)}
    \item{TEMP}{Temperature (\eqn{^\circ}{deg}C)}
    \item{PRES}{Atmospheric pressure (hPa)}
    \item{DEWP}{Dew point temperature (\eqn{^\circ}{deg}C)}
    \item{RAIN}{Precipitation amount (mm)}
    \item{WSPM}{Wind speed (m/s)}
