CHELSA-monthly is a global, kilometer-scale climate dataset generated with the CHELSA downscaling model. It consists of monthly aggregated surface variables summarized as monthly means or (in some cases) monthly accumulations.
WSL (Swiss Federal Institute for Forest, Snow and Landscape Research)
Total cloud area fraction, reported as a percentage, for the whole atmospheric column.
Monthly ratio of precipitation to potential evapotranspiration; indicator of climatic water availability.
Total potential evapotranspiration for the month assuming unlimited water availability, calculated using Penman-Monteith.
Precipitation including liquid and solid phases.
Surface Downwelling Shortwave Flux in Air
Surface solar irradiance for UV calculations.
Near-surface, usually 10 meter, wind speed.
Standardized Precipitation Evapotranspiration Index
Standardized climatic water balance index over a 12-month integration period.
Standardized precipitation anomaly index over a 12-month integration period.
Near-surface, usually 2 meter, air temperature.
Daily Maximum Near-Surface Air Temperature
Maximum near-surface, usually 2 meter, air temperature.
Daily Minimum Near-Surface Air Temperature
Minimum near-surface, usually 2 meter, air temperature.
Difference between saturation vapor pressure and actual vapor pressure.
