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.

RADARSAT-1 Data Access and Tools
RADARSAT-1 collected Synthetic Aperture Radar (SAR) data from 1995-2008, archived at NASA’s Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC). The instrument had worldwide coverage, with extensive coverage of Arctic Ocean sea ice. The datapool contains ASF DAAC standard beam odd frames, as well as the first and last frame of each imaged swath. The datapool also contains all Fine Beam 1 frames in a CEOS — Level 0 and Level 1 framed format.
