Vertical land subsidence rates are produced using the methodology of Interferometric Synthetic Aperture Radar (InSAR). The input data are 163 Sentinel-1 derived interferograms produced using the Advanced Rapid and Imaging system of NASA JPL, available at: https://asf.alaska.edu. These data are accessed and preprocessed using the ARIA-tools library (https://github.com/aria-tools/ARIA-tools). The data are then subject to time-series processing using the Small Baseline Subset algorithm as implemented in the MintPy software (https://github.com/insarlab/MintPy). Details on pixel selection and geodetic tie-ins are included in the Supplementary Materials of the published manuscript.
