Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) is a 30+ year rainfall dataset (Funk et al., 2014). It uses a combination of satellite and station data to provide either daily or pentand (5 day) total rainfall. CHIRPS is useful for environmental or drought monitoring through precipitation based drought indices and trend analysis.
Precipitation: Total precipitation (depth)
Standard Precipitation Index (SPI): A multi-timescale drought drought index based on precipitation (McKee 1993)
