CHIRPS
Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) from Climate Hazard Center (CHC), Department of Geography, University of California Santa Barbara - https://www.chc.ucsb.edu/data/chirps is a 35+ year quasi-global rainfall data set. Spanning 50°S-50°N (and all longitudes) and ranging from 1981 to near-present, CHIRPS incorporates CHC's in-house climatology, CHPclim, 0.05° resolution satellite imagery, and in-situ station data to create gridded rainfall time series for trend analysis and seasonal drought monitoring.
To support current project, GOST utilise CHIRPS's monthly rainfall data.
