Mitigation of atmospheric phase delay in InSAR time series using ERA-interim model, GPS and MODIS data: application to the permafrost deformation in Hurd Peninsula, Antarctica
In this study we compare the results obtained using three different atmospheric datasets for the mitigation of atmospheric effects in TerraSAR-X imagery. The used datasets are: ERA-interim re-analysis model, MODIS sensor precipitation water vapour data and GPS derived precipitable water vapour (PWV)...
