About the DAAC

The NSIDC Distributed Active Archive Center (DAAC) processes, archives, documents, and distributes data from NASA's Earth Observing System (EOS) satellites, airborne campaigns, and field measurement programs. The NSIDC DAAC focuses on the cryosphere and related topics, including snow, sea ice, glaciers, ice sheets, frozen ground, soil moisture, and climate interactions.

The NSIDC DAAC is part of NASA's Earth Observing System Data and Information System (EOSDIS). The DAACs, managed by NASA’s Earth Science Data and Information System Project (ESDIS), offer thousands of Earth system science data products and associated services to a wide community of users. Each DAAC serves one or more specific Earth science disciplines and provides its user community with data products, data information, user services, and tools unique to its particular science.

CoreTrust

The NSIDC DAAC is a CoreTrustSeal certified Regular Member of the World Data System, an Interdisciplinary Body of the International Science Council (ISC; formerly ICSU). The NSIDC is one of 12 DAACs that form the network of organizations which the ESDIS Project represents as a Network Member of the WDS.

User Working Group

The NSIDC DAAC has a User Working Group (UWG) of scientists from the fields of research that the DAAC serves. The working group also includes the DAAC Scientist, the NASA Cryosphere Scientist, and the EOSDIS Project Scientist.

A formal Charter has not been written for the UWG. The UWG operates under the following terms of reference.

  • Reviewing the progress and performance of the DAAC relative to the NSIDC DAAC’s missions;
  • Representing the user community in the development and operation of the NSIDC DAAC products and services;
  • Recommending specific data products and services to NASA and the NSIDC DAAC;
  • Providing strategic guidance and advice to NASA and NSIDC on the NSIDC DAAC objectives, priorities, target user communities, implementation approaches, and other issues.

For further details, refer to the UWG Terms of Reference.

    Feedback may be sent to the UWG Chair, Dr. Lawrence Mudryk (lawrence.mudryk@canada.ca), or DAAC UWG Coordinator Amanda Leon (amanda.leon@colorado.edu) at the NSIDC DAAC.
