Ground movement maps from radar (Sentinel-1)

Sentinel-1 Interferograms
deformation NASA ASF Level 2 netCDF-4PNGJSON
In plain English

What it measures. Maps that reveal how the ground has shifted, showing surface movement from uplift, sinking, or shaking, by comparing radar images of the same place over time.

How it's made. Generated by JPL's ARIA project from Sentinel-1 radar data as interferograms (a technique called InSAR that detects ground deformation).

How & where you'd use it. Supports study of earthquakes, volcanoes, and land subsidence or uplift in tectonically active regions.

Official description

Level-2 interferometric products generated by the Jet Propulsion Lab (JPL) ARIA project. The creation, discovery, and distribution of these products support InSAR science around tectonically active regions, volcanoes, or areas of subsidence/uplift. The generation of the ARIA-S1-GUNW products was in part funded through collaborations with the AWS Open Data Program and NASA ROSES.
