ABSTRACT
Global rainfall products of high spatial and temporal resolutions have been provided using combined data from passive microwave (PMW) sensors in low Earth orbit infrared (IR) radiometers geostationary (GEO). This study compared six satellite estimates around Japan with reference to a ground-radar dataset calibrated by rain gauges the Meteorological Agency (JMA) January through December 2004. Validation results tended be better for interpolation based upon morphed technique GEO IR information. Satellite were poor light during warm season very heavy rainfall. Further analyses conducted terms sources surface types. Effective performance merger PMW sounders over ocean was verified radar validation, addition best imagers. Overall, validation best, mountainous regions worst. Performance coasts small islands, due problem retrievals. focused on hydrometeor profiles orographic Japanese Archipelago, which could related
