bias. The Jet Propulsion Laboratory (JPL) Observational Products for End-users from Remote Sensing Analysis (OPERA) project will utilize this approach for its upcoming Surface Displacement product (DISP), which will be freely distributed to the community through the NASA Data Active Archive Center at the Alaska Satellite Facility. To demonstrate its utility to the SCEC community in advance of the upcoming, official validated release of the Surface Displacement products from Sentinel-1 (DISP-S1) product in December 2024, we are participating as stakeholders of the OPERA DISP product suite as part of a co-development effort with the OPERA Stakeholder Engagement Program (SEP). Here, we present on efforts to generate interseismic line-of-sight velocities over southern California using sample (DISP-S1) products. We expand upon and update our existing workflows developed under previous SCEC efforts and methods to derive time-series and velocity products and align them to GNSS displacement time-series. We will make our developments publicly available to the community.
