\title{Minimal Seed Dataset for Synthetic Data Generation}
\format{
A data.table with 1,319 rows and 10 variables:
\describe{
\item{s_id}{Station identifier (factor)}
\item{lon}{Longitude in decimal degrees}
\item{lat}{Latitude in decimal degrees}
\item{alt}{Altitude in meters}
\item{genus}{Plant genus (factor)}
\item{species}{Full species name (factor)}
\item{phase_id}{BBCH phenological phase code (integer)}
\item{year}{Observation year}
\item{day}{Day of year (DOY) of the phenological event}
\item{country}{Country name}
}
}

Derived from PEP725 Pan European Phenology Database \url{https://pep725.eu/}
}
\description{
A small subset of phenological data suitable for use with \code{\link{pep_simulate}}
to generate synthetic phenological datasets. This dataset contains real structure
but limited scope, making it suitable for package examples and testing.
}
\details{
This dataset includes observations for:
\itemize{
\item \strong{Species}: Triticum aestivum (wheat), Vitis vinifera (grapevine),
Malus domestica (apple)
\item \strong{Phases}: BBCH 10 (emergence), 60 (flowering), 65 (full flowering)
\item \strong{Countries}: Austria, Germany-South
\item \strong{Years}: 1990-2015
\item \strong{Stations}: 30 stations
}

pre-generated synthetic data from the package repository.
