Description

These data contain vertical rates (mm/yr) of surface land displacements and their associated uncertainties from 2015-03-15 to 2019-06-01.

They are associated with Buzzanga, B. A., Bekaert, D. P. S., Hamlington, B. D., and Sanga, S. (2020), "Towards Sustained Monitoring of Subsidence at the Coast Using InSAR and GNSS: An Application in Hampton Roads, Virginia. Geophysical Research Letters.

Methodology

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.
