According to the characteristics of AMSR-E, a simulation study is conducted on the derivation of the integrated water vapor in non-raining cloud areas over the oceans by the physical-statistical method, and a preliminary validation is implemented with the measured brightness temperature. 针对AMSR-E的特点,采用物理统计方法,对洋面非降水云区水汽总量(V)的反演进行了模拟研究,并用实测亮温数据对反演算式进行了初步验证。
