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.
Delivery of Suomi National Polar-orbiting Partnership (Suomi NPP) satellite data products will cease on November 1, 2026. Data users should transition now to alternative products from NOAA-21 and NOAA-20.
