  • Fig. 1 Synergy between surface deformation, groundwater level, and precipitation data.

    (A) Our LOS velocity obtained from interferometric processing of the 69 C-band SAR images acquired by Sentinel-1 satellite during November 2014 through October 2017. (B) Time series of LOS deformation at three locations marked in (A) with color-coded circles. Detrended time series are also provided (dashed lines). Arrows show timing of annual transient uplifts. The horizontal red line marks the period that aquitard undergoes residual compaction (residual comp.), while the black line shows the period that residual compaction nearly halts (no residual comp.). (C) Time series of groundwater level change measured at five wells, whose locations are marked in (A) with color-coded squares (source: water.ca.gov). For comparison purpose, the time series are shifted to start at zero level at the beginning of the time. Site codes are W1: 361753N1196460W001 (longitude, −119.6460; latitude, 36.1753), W2: 361158N1196258W001 (longitude, −119.6258; latitude, 36.1158), W3: 361700N1196900W001 (longitude, −119.6900; latitude, 36.1700), W4: 361900N1195800W001 (longitude, −119.5800; latitude, 36.1900), and W5: 360900N1196600W001 (longitude, −119.6600; latitude, 36.0900). (D) Monthly precipitation (black bars) and monthly anomalies compared with 18-year average (red curve) for Tulare Basin (source: pmm.nasa.gov/trmm).
