星载测雨雷达宽广的观测区域内往往缺乏雨滴谱的测量，本项研究拟利用TOGA-COARE试验期间取得的同步微物理和机载测雨雷达资料进一步检验并完善我们提出的雨滴谱优化新方案。在新方案的基础上，利用GAMEX-3试验中同时同地的机载雷达资料检验TRMM星载测雨雷达资系目煽啃裕⒏慕肨RMM雷达资料进行降雨量反演的方法。

A new DSD optimization approach was developed using the sea surface echo of rain radar. This research aims at testing and ameliorating this approach through the synchronal microphysical and airborne radar data which are obtained during the TOGA-COARE experiment. On the basis of the new approach, we validate the TRMM spaceborne rain radar data through the airborne data obtained during the GAMEX-3 experiment and then ameliorate the rainfall rate retrieval algorithms.
