Global Precipitation Mission (GPM)

GPM is the follow-on augmented mission of TRMM mission

To improve accuracy of long and short-term weather forecasts (and meteorology, climatology)

To improve water resource management in river control and irrigation systems (and hydrology, agrometeorology)

Core SatelliteTRMM Era GPM Era

Global Rainfall Map (GSMaP) in Near Real Time

WGISS 29 @ Bonn, Germany 17-21 May, 2010

Hourly global rainfall maps are available four hours after observation. This system is based on rainfall algorithm developed by the GSMaP (Global Satellite Mapping of Precipitation) project.
