ng ITRF 2014 reference frame, we integrate this InSAR time series with continuous GNSS coordinate time series datasets from the NASA MEaSUREs ESESES project to produce a combined InSAR/GNSS time series. We present updated time series for Sentinel-1 tracks 166, 173, 071, 144, 042, and 115, while additional ascending track processing is ongoing. This 7+ years of data allows us to observe and explore a variety of ongoing crustal processes in both northern and southern California, including earthquake cycle deformation (inter-, co-, and post-seismic motions), fault creep along multiple California faults, hydrological effects, and the effects of anthropogenic fluid extraction and influence. We estimate updated interseismic velocities with uncertainties estimated from a combination of white+flicker noise. In addition, we measure the ongoing effects of postseismic deformation around the 2019 Ridgecrest earthquake sequence.
