ASF Displacement Portal shows OPERA-DISP local surface velocity between 2016 and 2024 for an agricultural region on the Nevada-California border. Blue shades represent movement away from the observing satellite (primarily downward motion) and red shades represent motion towards the observing satellite (primarily upward motion). The lower part of the image shows an OPERA-DISP  time series  for a specific location that is marked with a “1” on the map. X-axis is time in years, y-axis is vertical displacement

The top image is the ASF Displacement Portal displaying the OPERA-DISP local surface velocity between 2016 and 2024 for an agricultural region on the Nevada-California border. The bottom image displays a time series of the OPERA-DISP data for a specific location within this area of interest marked with a "1” on the top map. Local displacement in meters between August 7, 2016, through November 15, 2021, shows subsidence related to groundwater withdrawal. 

Many scientists are interested in using interferometric synthetic aperture radar (InSAR) data to monitor the motion of Earth’s surface, but the analyses required can be complex, and the data are often challenging to work with. To simplify these analyses, the Jet Propulsion Laboratory (JPL) Observational Products for End-Users from Remote Sensing Analysis (OPERA) team has created an OPERA Surface Displacement (OPERA-DISP) dataset. This dataset provides InSAR-derived surface displacement measurements across most of North America and is now available via NASA’s Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC).

To support data users working with this product, ASF DAAC has also launched the ASF Displacement Portal — an open-source web interface that offers intuitive spatial browsing and direct exploration of the OPERA-DISP dataset. Join us to learn more about the OPERA-DISP product and the portal that enables its exploration.

The OPERA-DISP solution is a deliverable of the Satellite Needs Working Group (SNWG), an interagency effort of the U.S. Government dedicated to identifying and addressing Earth observation needs across U.S. civilian federal agencies.
