The data is calibrated seasonally and regionally with varying climatological calibration to the Final Run, which adjusts the Early based on the climatological relationship between Early and monthly gauge data. Input precipitation data 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.Credits:Huffman, G.J., E.F. Stocker, D.T. Bolvin, E.J.
