CLImate GENerator (CLIGEN) is a stochastic weather generator that produces daily and sub-daily timeseries of weather variables. This gridded CLIGEN parameterization complements existing coverage for South America and Africa by adding new coverage for Central America, the Caribbean, the Middle East, South Asia, Southeast Asia, Australia, New Zealand, and various islands. This parameterization used the methodology and trained machine learning models discussed in a dataset article by Fullhart et al. (2022), https://doi.org/10.1080/20964471.2022.2136610. The primary dataset for South America and Africa may also be found in Ag Data Commons at https://doi.org/10.15482/USDA.ADC/1524754.
The data are formatted as CLIGEN *.par files, which are the only required input for CLIGEN. The files are contained in the "Grid Files" download with n=37105 files. The files are labeled according to grid point lat/lon coordinates (WGS84) in decimal degrees. The labeling convention uses 'N' and 'E' (north, east) to represent coordinates with a positive sign and 'S' and 'W' (south, west) to represent coordinates with a negative sign.
