Precipitation (5-Day)

Quasi-global precipitation data that incorporates satellite imagery with in-situ station data

  • Last update: -

CHIRPS data, production led by the Climate Hazards Group at University of California, Santa Barbara (CHG UCSB), is a 30+ year quasi-global rainfall dataset. This data set spans 50°S-50°N (and all longitudes), starting in 1981 and spanning to near-present. As of February 12, 2015, version 2.0 of CHIRPS is complete and available to the public. CHIRPS incorporates 0.05°-resolution satellite imagery with on-the-ground precipitation station data to create gridded rainfall time series. Satellite data are derived from both microwave and infrared sensors. On-the-ground precipitation station data come from the Agromet Group of the Food and Agriculture Organization of the United Nations (FAO) and the Global Historical Climate Network (GHCN). Two CHIRPS products are produced operationally: a rapid preliminary version and a later final version. The preliminary CHIRPS product is available, for the entire domain, 2 days after the end of a pentad (2nd, 7th, 12th, 17th, 22nd, and 27th). The preliminary CHIRPS uses two station sources: GTS and Mexico. The final CHIRPS product takes advantage of several other station sources and is complete sometime in the 3rd week of the following month. Final products for all times/domains/formats are calculated at that time. Resource Watch shows only a subset of the dataset. For access to the full dataset and additional information, see the Learn More link.

Climate Hazard InfraRed Precipitation with Stations (CHIRPS)

Cautions

CHIRPS precipitation data is produced using a combination of satellite precipitation estimates and station data. Both of these measures have limitations which impact the CHIRPS precipitation estimates. Validations show variations of bias in different regions and seasons. More analysis of CHIRPS performance, especially at sub-seasonal scales, will be required in the future.
