The ORNL DAAC is operated by Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee, and is a member of the Remote Sensing and Environmental Informatics Group of the Environmental Sciences Division (ESD).

If you have questions for the ORNL DAAC, please contact the User Services Office.


The ORNL DAAC is proud to be a CoreTrustSeal Certified Repository. CoreTrustSeal is an international, community based, non-governmental, and non-profit organization promoting sustainable and trustworthy data infrastructures.

Mission

Toggle Mission

The mission of the ORNL DAAC is to assemble, distribute, and provide data services for a comprehensive archive of terrestrial biogeochemistry and ecological dynamics observations and models to facilitate research, education, and decision-making in support of NASA's Earth Science.

The ORNL DAAC's goals are to:

  • Serve as the primary data repository for data derived from NASA's Terrestrial Ecology program and Carbon Cycle Science and Ecosystems focus area.
  • Provide ground- and aircraft-based data to assess the accuracy and uncertainty of NASA's Earth Science missions.
  • Work with NASA to develop best practices, tools, and training for scientists who generate and use NASA Earth-observing data.
  • Facilitate synthesis and analysis by providing and integrating the diverse data required to address critical questions.

User Working Group

Toggle User Working Group

The ORNL DAAC User Working Group (UWG) is an external advisory group established by EOSDIS and tasked to:

  • Assist in defining and accomplishing the ORNL DAAC's goals.
  • Provide oversight and guidance on ORNL DAAC activities, including dataset acquisition, development of value-added products, user support, development activities, and operational functions.
  • Recommend annual work plans and advise on long-term planning.
  • Review interactions and agreements between NASA's Earth Science missions and the ORNL DAAC.

The UWG meets once per year to review the status of ORNL DAAC operations and to provide recommendations. Additional information about the responsibilities of the UWG can be found in the ORNL DAAC UWG CharterPDF.

The UWG is interested in hearing from users on how to improve the ORNL DAAC web platform, tools, and services, or about data that the ORNL DAAC should pursue. To provide input, contact the ORNL DAAC Chief Scientist.
