Short summary
Currently, the atmospheric phase delay is one of the most critical issues in InSAR deformation monitoring. We applied the proposed GACOS-corrected InSAR stacking method in the North China Plain and analysed its performance. Deformation maps revealed by InSAR stacking with and without GACOS corrections showed that GACOS could mainly remove the topography-related and long wavelength signals.
