Abstract

Differential Interferometric Synthetic Aperture Radar (D-InSAR) has been widely used to study the co-seismic displacement field of earthquakes. With the development of D-InSAR technique, the removal of the atmospheric effect has been the main focus points of research to reduce the InSAR LOS displacement measurement error. Previous studies have shown that the MERIS water vapor product is one of the best choices for ASAR data to reduce the atmospheric effect in cloudless weather conditions. In this paper, we use the combination of the simulated results with WRF model and MERIS water vapor product to reduce the atmospheric effect in some cloudy weather condition.
