ASF DAAC

Alaska Satellite Facility Distributed Active Archive Center

NASA's Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC) specializes in collecting, processing, archiving, and distributing satellite and airborne-acquired synthetic aperture radar (SAR) data. The DAAC strives to provide the fastest and most reliable data delivery possible and is committed to developing the tools, services, and support that make SAR more powerful and easier to use.

ASF DAAC leads the way in cloud computing and can provide the expertise to help you make the move into this computing environment. ASF services such as HyP3 and OpenScienceLab can remove obstacles that can make Big Data processing frustrating.

Data archived by ASF DAAC are or have been supplied by SAR instruments on many different space-based and air-based platforms, including:

  • NASA’s Soil Moisture Active Passive (SMAP), Airborne Synthetic Aperture Radar (AIRSAR), Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR), Spaceborne Imaging Radar-C (SIR-C), and Seasat
  • ESA (European Space Agency) Sentinel-1, European Remote Sensing Satellite (ERS) 1 and 2 (ERS-1 and ERS-2)
  • Japan Aerospace Exploration Agency (JAXA) Japanese Earth Resources Satellite (JERS-1) and Advanced Land Observing Satellite (ALOS)
  • Canadian Space Agency (CSA) RADARSAT-1

ASF DAAC is the data hub for the upcoming NISAR mission. NASA, in partnership with the Indian Space Research Organization (ISRO), has developed the NASA-ISRO SAR (NISAR) platform to measure changes on Earth’s surface with unprecedented precision.
