    • NESDIS Level 3 Blended Enterprise Rainfall Rates (ENTRAIN)

    Metadata Updated: December 12, 2025

    The NESDIS Enterprise Rainfall Rates (ENTRAIN) algorithm produces instantaneous rainfall rate maps for operational flood forecasting. The algorithm identifies raining pixels and derives rain rates on a pixel level from infrared (IR) imagery. Its calibration is based on matches of IR data with microwave (MW) derived rainfall rates, which are considered to be the most accurate estimates of instantaneous rainfall rate available from satellite data. The RR algorithm inputs include Level-1b IR observations from the ABI, AHI, and FCI instruments onboard the GOES, Himawari, and MTG satellites and ancillary MW rainfall rates from the NESDIS Blended Rain Rate product. The RR algorithm is based on the Self-Calibrating Multivariate Precipitation Retrieval (SCaMPR) algorithm. The data are produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS) and are distributed as gridded, 2km files in the netCDF-4 file format with attributes included.
