摘　　要：经检验发现 ,由国家卫星气象中心反演并投入业务使用的GMS 5卫星红外估计降水量产品性能在我国存在一定的区域差异。利用实测雨量对卫星估计降水量产品进行优化处理 ,结果显示优化后的卫星估计降水量在全国各气候分区都有不同程度的改善。The regional inconsistencies among the performances of GMS 5 infrared band rainfall estimations in China released by the National Satellite Meteorological Center are found by regional tests. The raingauge measurements were applied to optimize the satellite rainfall estimation products. The analysis shows that after the optimization, the satellite rainfall estimations for all the climatic regions in China are improved significantly, and the products could therefore have more extensive applications.
