Rainfall estimates (CHIRPS)

Date modified: 12 January 2022

Aperçu du produit


Digital Earth Africa (DE Africa) provides free and open access to a copy of the Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) monthly and daily products over Africa. The CHIRPS rainfall maps are produced and provided by the Climate Hazards Center in collaboration with the US Geological Survey, and use both rain gauge and satellite observations.

The CHIRPS-2.0 Africa Monthly dataset is regularly indexed to DE Africa from the CHIRPS monthly data. The CHIRPS-2.0 Africa Daily dataset is likewise indexed from the CHIRPS daily data. Both products have been converted to cloud-opitmized GeoTIFFs, and can be accessed through DE Africa’s Open Data Cube. This means the full archive of CHIRPS daily and monthly rainfall can be easily used for inspection or analysis across DE Africa platforms, including the user-interactive DE Africa Map.

A Jupyter Notebook which demonstrates loading and using CHIRPS datasets in the Sandbox is also available.

This page details how to access CHIRPS products through DE Africa platforms. For more information on the dataset, see the official CHIRPS website:

« Estimating rainfall variations in space and time is a key aspect of drought early warning and environmental monitoring. An evolving drier-than-normal season must be placed in a historical context so that the severity of rainfall deficits can be quickly evaluated. However, estimates derived from satellite data provide areal averages that suffer from biases due to complex terrain, which often underestimate the intensity of extreme precipitation events. Conversely, precipitation grids produced from station data suffer in more rural regions where there are less rain-gauge stations. CHIRPS was created in collaboration with scientists at the USGS Earth Resources Observation and Science (EROS) Center in order to deliver complete, reliable, up-to-date data sets for a number of early warning objectives, like trend analysis and seasonal drought monitoring. »

Technical Information

Climate Hazards Group InfraRed Precipitation with Station 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 the Climate Hazards group Precipitation climatology (CHPclim) that incorporates satellite information to represent sparsely gauged locations, 0.05° resolution satellite-only CCD-based Climate Hazards group Infrared Precipitation (CHIRP) estimates, and in-situ station data to create gridded rainfall time series for trend analysis and seasonal drought monitoring.

For more information on the algorithm used to generate the CHIRPS datasets visit the CHIRPS pulication.
