Summary:<\/span><\/p>

GPM IMERG Final Precipitation Rate L3 V07(GPM IMERG Final Precipitation L3 Daily 0.1 degree x 0.1 degree V07 (GPM_3IMERGDF V07))is an image service derived from the Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (GPM) Early dataset.<\/span><\/p>

The web service shows total precipitation (mm) for the date range outlined by aggregating 30-minute intervals. This data is shown as cumulative (from start date) and on a daily basis.<\/span><\/p>

IMERG is an algorithm that estimates precipitation rate from multiple passive microwave sensors in the GPM constellation, the GPM Dual-Frequency Radar, and infrared (IR) sensors mounted on geostationary satellites. Currently, the near-real-time Early estimates have no concluding calibration. Briefly describing the Early Run, the input precipitation estimates computed from the various satellite passive microwave sensors are intercalibrated 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 morphed\" and combined with microwave precipitation-calibrated geo-IR fields to provide half-hourly precipitation estimates on a 0.1°x0.1° (roughly 10x10 km) grid over the globe. Precipitation phase is computed using analyses of surface temperature, humidity, and pressure.<\/span><\/p>
