NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR), a reconfigurable, polarimetric L-band SAR, is specifically designed to acquire airborne repeat track SAR data for differential interferometric measurements. Differential interferometry can provide key deformation measurements, and is important for studies of earthquakes, volcanoes, and other dynamically changing phenomena.
We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.
