Abstract
Current version of the over-land Global Satellite Mapping of Precipitation (GSMaP) algorithm for microwave sounder tends to underestimate rain areas because of missing warm rain due to scattering-based algorithm only applied over land. Therefore we develop a new rain/no-rain classification (RNC) method using channels such as 89, 150, 186 and 190 GHz to detect the warm rain. In order to estimate the performance of the revised RNC method, the AMSU-PR matched-up cases are used. The result shows that the shallow precipitation over land, which is missed by the original RNC method, is detected by the revised RNC method.
