The National Aeronautics and Space Administration (NASA) Earth Science Data and Information System (ESDIS) Project is a part of the Earth Science Projects Division under the Flight Projects Directorate at Goddard Space Flight Center. As key components of ESDIS, 12 interlinked Distributed Active Archive Centers (DAAC) are operated by a distributed network of independent facilities across the United States - including the NASA DAAC operated by the Alaska Satellite Facility (ASF).

The ASF DAAC specializes in synthetic aperture radar (SAR) data collection, processing, archiving, and distribution. These data are, or have been, supplied by SAR sensors on many different spaceborne and airborne platforms, including:
