| Abstract: | Using the matched data between the measurements of Tropical Rainfall Measure ment Mission Microwave Imager (TRMM/TMI) and those of ground based weather rad ar at Fuyang during the Intensive Observation Periods (IOPs) of GEWEX Asian Mons oon Experiment-Huaihe River Basin Experiment(GAME/HUBEX), the proper identificat ion of rain area is obtained by the dynamic cluster classification method, and a passive microwave rainfall retrieval algorithm that rain rate is a function of the scattering index and the polarization corrected temperature at 85.5 GHz is e stablished. The comparison between our retrieval test and the rainfall retrieval from the TMI and TRMM precipitation radar (PR) at the same time provided by NAS DA of Japan shows that the algorithm used in this paper is successful in retriev ing the distribution of rain rate and identifying the areas of rainfall over land. |
