ERA-Interim资料和NeQuick电离层模型用于D-InSAR沉降监测的可靠性研究
RELIABILITY STUDY ON SEDIMENTATION MONITORING FOR D-INSAR BY USING ERA-INTERIM DATA AND NEQUICK MODEL
摘要
Abstract
Four images for ALOS PALSAR of the track 474 before and after Wenchuan earthquake are processed by the software ROI_PAC,and then the tropospheric and ionospheric delay are corrected by ERA-Interim data and NeQuick model.The sedimentation is compared with that derived from five GPS observations,the results show that the mean value of the differences between the sedimentation derived from D-InSAR and that from GPS observations is 0.104 m,which is 0.057 m when the sedimentation derived from D-InSAR which the tropospheric and ionospheric delay are corrected.This illuminates that the accuracy of the sedimentation from D-InSAR is improved after the tropospheric and ionospheric delay are corrected.关键词
