CHIRPS
Free
Gauge-blended satellite rainfall at 0.05°, daily, since 1981 — the standard for drainage work in data-sparse regions.

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
Gov-Public
NASA's 30-minute, 0.1° global precipitation record — the highest time resolution of any satellite rainfall product.
MSWEP
Freemium
Precipitation that optimally blends gauges, satellites and reanalysis at every grid cell — 3-hourly, 0.1°, global.
NASA Earthdata Search
Gov-Public
The unified search portal across every NASA Earth-observation archive — SRTM, MODIS, SMAP, GPM, GRACE and more.
PERSIANN-CDR
Free
A neural-network satellite rainfall climate data record, daily, 0.25°, purpose-built for long-term trend studies.
