摘要
文中利用MERIS数据，使用平差手段，进行时序InSAR水汽反演。选取南加州作为实验区，以MERIS作为验证数据，结果显示两者的空间相关系数为0．92，PWV差异的标准差约为1．5mm，具有较强的一致性，说明本文反演方法的可靠性。
The inversion of water vapor with a set of SAR interferograms and MERIS datas was investigated using the surveying adjustment method in this paper. Taken Southern California as an experimental zone, and one MERIS im- age as the validated data, the results showed that the spatial correlation coefficient of the InSAR -retrieved and the MERIS - measured PWV （Precipitable Water Vapor） was 0.92, and the standard deviation of their difference was about 1.5 ram. And the results demonstrated that the method investigated in this paper was feasible to retrieve non - differential water vapor based on time series InSAR.
