Satellite Precipitation Datasets
Gauge networks thin out fast outside wealthy countries, and satellite precipitation fills the gap: CHIRPS, GPM IMERG, PERSIANN-CDR and MSWEP blend infrared, microwave and gauge data into gridded, near-global rainfall records running back decades. Indexed here are the datasets themselves, ready to feed a rainfall-runoff model wherever gauges fall short.
GPM IMERG
