Atmospheric water vapor effect removal of inSAR interferogram in southern california region

In recent years, the Differential Interferometric Synthetic Aperture Radar (D-InSAR) technique has been proved to be an effective method to monitor the ground deformation. When the radar signal propagates in the atmosphere, its phase will be delayed. Previous studies have shown that water vapor is the most important factor for the atmospheric effect in the D-InSAR processing. In this paper, we choose the southern California region to analyze the atmospheric water vapor effect of the D-InSAR interferogram.EI
