GPM IMERG Final precipitation rate is derived from the Integrated Multi SatellitE Retrievals for GPM (Global Precipitation Measurement) algorithm. Precipitation rate measurements are taken from multiple satellite based passive microwave sensors in the GPM constellation. The Final Run IMERG data product is distinct in that it combines data from ground sources and satellite-based observations to provide research quality precipitation rate data. Precipitation rate is depicted in mm/hr in 30-minute intervals, beginning on June 1, 2000. The Final, satellite-gauge product is available ~3.5 months after the observation month, and includes both forward and backward morphing and monthly gauge analyses. In the post-real-time Final Run, the multi-satellite half-hourly estimates are adjusted so that they sum to the Final Run monthly satellite-gauge combination. Briefly describing the Final Run, the input precipitation estimates computed from the various satellite passive microwave sensors are inter-calibrated to the Combined Radar-Radiometer Algorithm (CORRA) product (because it is presumed to be the best snapshot Tropical Rainfall Measuring Mission (TRMM)/GPM estimate after adjustment to the monthly Global Precipitation Climatology Project Satellite-Gauge (GPCP SG)), then forward/backward morphed and combined with microwave precipitation-calibrated geo-IR fields, and adjusted with seasonal GPCP SG surface precipitation data to provide half-hourly and monthly precipitation estimates. |
