IMP GACOS-based atmospheric phase distribution of all 181 interferograms in (a) HH and (b) VV. Each colored column represents the IMP atmospheric phase distribution in the corresponding IDth interferogram (ID∈ [1, 181]). Per column, the color depicts the area of the Normal distribution. The interferogram index ID information is listed in Table A1.

... GACOS-based atmospheric phase values were assigned to all CCSs and TCSs, and assisted in phase unwrapping and parameter estimation. Figure 4a,b show the GACOS-based atmospheric phase distribution of all 181 interferograms for IMPs in HH and VV, respectively. Every column in Figure 4a,b shows the IMP atmospheric phase distribution (normally distributed) in the designated interferogram, albeit showing the difference in the IMP registry in HH and VV, the expectation of the GACOS-based atmospheric phase in HH and VV both ranges between −13 and 6 radians, and the dispersion limits' [0. ...

... study used the GACOS weather model to remove the atmospheric phase, which is at the level of a few centimeters for our case (see Figure 4 in Section 4.1.1). Due to the lack of ground truth data, it is not practically feasible to assess the accuracy of the GACOS-based atmospheric phase result. ...
