NASA's Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC) is located in the Geophysical Institute at the University of Alaska, Fairbanks. ASF DAAC is supported by NASA to acquire, process, archive, and distribute synthetic aperture radar (SAR) data from polar-orbiting satellite and airborne sensors to advance Earth science research. Most of the datasets at ASF DAAC, including Copernicus Sentinel-1, are open access and freely available to the public for download.

Synthetic Aperture Radar (SAR) Data

ASF DAAC archives data from around the world. This includes data from the Copernicus Sentinel-1 constellation, Canadian RADARSAT-1, European Remote Sensing Satellite-2 (ERS-2), the Japanese ALOS PALSAR, European Remote Sensing Satellite-1 (ERS-1), Japanese Earth Resource Satellite-1 (JERS-1), and the NASA SMAP and Seasat satellites. In addition, ASF DAAC archives and distributes AirSAR and UAVSAR - two airborne SAR sensors operated by NASA.
