Multi-satellite Global Satellite Mapping of Precipitation (GSMaP) - Design and Products -

Estimation of the global distribution of precipitation with high accuracy and resolution has long been one of the major scientific goals. Precipitation map on a global basis is important for modeling of the water cycle, maintaining the ecosystem environment, agricultural production, improvements of weather forecast precision, flood warning, and so on. GSMaP (Global Satellite Mapping of Precipitation) is a project aiming (1) to produce high-precision and high-resolution global precipitation map using satellite-borne microwave radiometer data, (2) to develop reliable microwave radiometer algorithms, and (3) to establish precipitation map techniques using multi-satellite data for GPM.
