We offer hourly global rainfall maps in near real time (about four hours after observation) using the combined MW-IR algorithm with TRMM TMI, Aqua AMSR-E, GCOM-W1 AMSR2, DMSP SSM/I and SSMIS, NOAA-19 AMSU, MetOp-A AMSU and GEO IR data. Background cloud images are globally merged IR data produced by NOAA Climate Prediction Center (CPC), using IR data observed by JMA's MTSAT satellite, NOAA's GOES satellites and EUMETSAT's Meteosat satellites.

User Registartion for Near-Real-Time Data

Near-real-time products and images will be removed when reanalysis version data is uploaded. Reanalysis version data (GSMaP_MVK Ver.5.222) is processed by the latest algorithm and uses all available satellite data. We release reanalysis data from Mar. 2000 to Nov. 2010 to registered users of near-real-time data.
