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. Read about the Web Unification Project

Featured Tectonics Observation Method: Sentinel-1 C-band Synthetic Aperture Radar

The ESA (European Space Agency's) Sentinel-1A/B satellites are equipped with synthetic aperture radar (SAR) instruments that record continuous all-weather, day-and-night imagery. SAR energy beams can penetrate cloud and tree canopy cover to detect very small changes to the height, shape, and position of Earth surfaces. The ability of Sentinel-1 to capture detailed SAR images anywhere at any time makes them excellent tools for producing interferograms and digital elevation models to track the movement of Earth's plates.
