The TAPEER-BRAIN algorithm combines microwave and infrared observations to provide precipitation estimates and associated errors bars at the one-degree/one-day accumulated scale. It relies on rain detection from LEO microwave imagers (TRMM/TMI, F15/SSMI, F16/SSMIS, F17/SSMIS, F18/SSMIS, GCOMW1/AMSR2) and sounders (Megha-Tropiques/SAPHIR) as well as instantaneous precipitation retrievals from LEO microwave imagers using the BRAIN algorithm (Viltard et al, 2006). Those detections and rain rates estimates are then merged with full space/time resolution data from the thermal window channel onboard GEO platforms (MSG, Meteosat7/MSG-1 IODC, GOES-E, GOES-W, MTSAT, HIMAWARI). The product is further corrected statistically using the TRMM PR v7 near surface rain rates data.
