This gridded merged multi-satellite geostationary infrared (IR) brightness temperature product originates from the NOAA Climate Prediction Center (CPC), the National Centers for Environmental Prediction (NCEP), and the National Weather Service (NWS) and are hosted by NASA’s Goddard Earth Sciences Data and Information Services Center (GES DISC).

The datasets contain IR brightness temperature data (equivalent blackbody temps), merged from the European, Japanese, and U.S. geostationary satellites that have been active over the product’s period of record (METEOSAT-5/7/8/9/10, GMS-5/MTSat-1R/2/Himawari-8, and GOES-8/9/10/11/12/13/14/15/16), and gridded to 4-km every half hour on the latitude band 60°S-60°N.

Within GPM, this dataset is used to compute IR precipitation estimates that are input to NASA’s IMERG product.
