  description: 'The Integrated Multi-satellitE Retrievals for GPM (IMERG) algorithm
    combines information from the [GPM satellite constellation](https://gpm.nasa.gov/missions/gpm/constellation)
    to estimate precipitation over the majority of the Earth''s surface. This algorithm
    is particularly valuable over the majority of the Earth''s surface that lacks
    precipitation-measuring instruments on the ground. Now in the latest Version 06
    release of IMERG the algorithm fuses the early precipitation estimates collected
    during the operation of the TRMM satellite (2000 - 2015) with more recent precipitation
    estimates collected during operation of the GPM satellite (2014 - present). The
    longer the record, the more valuable it is, as researchers and application developers
    will attest. By being able to compare and contrast past and present data, researchers
    are better informed to make climate and weather models more accurate, better understand
    normal and extreme rain and snowfall around the world, and strengthen applications
    for current and future disasters, disease, resource management, energy production
    and food security.
