The Sentinel-1 data available from ASF (from both Sentinel-1A and Sentinel-1B) comprise a complete historical archive of Sentinel-1 synthetic aperture radar (SAR) data processed by the European Space Agency (ESA).
NASA's provision of the complete ESA Sentinel-1 synthetic aperture radar (SAR) data archive through the ASF DAAC is by agreement between the U.S. State Department and the European Commission (EC). As part of the Earth-observation Copernicus program, the Sentinel mission will provide scientists with accurate, timely, and easily accessible information to help shape the future of our planet. Content on ASF's Sentinel web pages is adapted from the ESA Sentinel-1 website.
