Climate Hazards Center InfraRed Precipitation with Station data (CHIRPS) est un ensemble de données quasi mondiales sur les précipitations, qui couvre plus de 30 ans. CHIRPS intègre des images satellite d'une résolution de 0,05° avec des données de stations in situ pour créer des séries temporelles de précipitations maillées pour l'analyse des tendances et la surveillance de la sécheresse saisonnière.
