GInSAR vertical surface displacements over the San Joaquin Valley, CA spanning April 2015 to October 2017
<p>A time series of vertical surface displacements over the San Joaquin Valley (SJV) spanning April 2015 to October 2017.</p> <p>Base Data: European Space Agency’s Sentinel-1A/B descending track 144; National Science Foundation Plate Boundary Observatory Global Positioning System (GPS) network; Southern California Earthquake Center’s Community Geodetic Model</p> <p>Time: 2015.04.01 – 2017.10.23, 51 acquisition times, 263 interferograms</p> <p>Processors/Software: GMTSAR, MATLAB</p> <p>Interferogram construction and unwrapping was performed in GMTSAR. GPS correction, time series inversion, and vertical projection was performed in MATLAB.</p> <p> </p> <p>This dataset was constructed following similar methods outlined in Neely et al., (2020).</p> <p>Neely, Wesley R., Adrian A.
