The polarization corrected temperature (PCT) derived from SSM/I 85 GHz data is used for the retrieval of rainfall rate over South China in the summer season. The 85 GHz PCT observed from space is strongly dependent on the emission and scattering by cloud and rain droplet particles. Hourly rain gauge measurement data were used to relate PCT with surface rainfall rate. Since the rainfall phenomena have large variabilities in time and space, a direct comparison between rain gauge measurement and satellite measurement is not adequate. On the other hand the rainfall rate distribution in a wide area does not change even if the measurement time is slightly different. Therefore the rainfall rate distribution measured with rain gauge and PCT change distribution were compared and a relationship between them is constructed. By applying it to SSM/I data, rainfall properties over the South China during periods from June to August of 1991-1995 were investigated.
