Abstract
Using Sentinel-1A data in 2021, the displacement of Tomur Glacier in the radar line of sight is obtained by repeated orbit differential interferometry. By introducing ice flow factor and combining glacier slope, the vertical deformation is extracted as the surface elevation change. The results of the study found that the overall average annual elevation change of Tomur Glacier decreased by -14.03m, with an average decrease of -0.26 . The reliability of the model was verified, and the results of the comparative study revealed that the glacier thinning rate has been increasing in recent years, and the trend of glacier retreat is becoming more severe.
