The Integrated Multi-satellitE Retrievals for GPM (IMERG) is a NASA algorithm that merges precipitation estimates from the constellation of passive microwave satellites in the Global Precipitation Measurement (GPM) mission with microwave-calibrated infrared estimates and monthly gauge analyses to produce a global, gridded, half-hourly precipitation record. IMERG intercalibrates, merges, and interpolates these inputs onto a 0.1 degree grid spanning the TRMM and GPM satellite eras.
