Comparisons of mean velocities from ascending Sentinel-1 (path 39) before and after the tropospheric delay correction. a Mean LOS velocities without correction; b, c mean velocities corrected for tropospheric delay by b the elevation-phase linear fitting method, c the ERA-I weather model, and d the GACOS weather model. The white dashed polygons in c and d indicate the regions showing significant LOS shortening after the correction
