About ORNL DAAC

The Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) for biogeochemical dynamics is one of the NASA Earth Observing System Data and Information System (EOSDIS) data centers managed by the Earth Science Data and Information System (ESDIS) Project, which is responsible for providing scientific and other users access to data from NASA's Earth Science Missions. ORNL DAAC is operated by the ORNL Environmental Sciences Division and is responsible for data archival, product development and distribution, and user support for biogeochemical and ecological data and models.

ORNL DAAC regularly partners with other DAACs on EOSDIS activities. In addition to the core EOSDIS partnership function, ORNL DAAC also partners with other organizations.

Who We Are

The ORNL DAAC is a data center in NASA's Earth Observing System Data and Information System (EOSDIS).

Mission Statement and Goals

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.

ORNL DAAC Data and Data Services are used to:

  • Understand terrestrial biogeochemical processes
  • Assess the accuracy and uncertainty of remote sensing products
  • Integrate process understanding within remote sensing observations
  • Develop, assess, and drive biogeochemical models
  • Educate future earth scientists
  • Provide information for decision-making activities

ORNL DAAC's Goals are to:

  • Serve as the primary active archive for biogeochemical dynamics data derived from NASA's field campaigns
  • Provide field data to assess the accuracy and uncertainty of NASA's remote sensing products
  • Work with NASA to develop best practices, tools, and training for data providers to generate terrestrial ecology and biogeochemical dynamics data for sharing and archival
  • Archive and disseminate regional and global data products for modeling and analysis
  • Archive and disseminate model source code to enable synthesis of results across modeling studies
  • Work with NASA to develop and use the best available technology to organize and present data to users
  • Facilitate interdisciplinary synthesis by providing and integrating diverse data required to address common hypothesis (across multiple scales, model-data intercomparison, etc.)

User Working Group

The ORNL DAAC User Working Group (UWG) provides guidance in defining and accomplishing the DAAC's science goals.

Partner Organizations


ORNL DAAC Partners

ORNL DAAC regularly partners with other DAACs on EOSDIS activities. In addition to the core EOSDIS partnership function, ORNL DAAC also partners with the following organizations.

ESDSWG

The Earth Science Data System Working Groups (ESDSWG) is a NASA organization that focuses on the exploration and development of recommendations derived from pertinent community insights of NASA's heterogeneous and distributed Earth science data systems.

ORNL DAAC staff participate in ESDSWG Working Groups.

ABoVE Working Groups

The Artic Boreal Vulnerability Experiment (ABoVE) Working Groups define standards of data management, services, models, variables, and products for ABoVE.

ORNL DAAC staff participate in the Core Variables & Standards and the Geospatial Products & Standards ABoVE Working Groups.

ESIP

The Federation of Earth Science Information Partners (ESIP Federation ) is a networked community that brings together science, data and information technology practitioners.

ORNL DAAC is a long-term member of the ESIP federation and is a member of many of the working groups.

ICSU / WDS

The International Council for Science World Data System (ICSU / WDS ) promotes stewardship and access to data and data services across a range of science disciplines.

ORNL DAAC is a member of the World Data System.

Data Centers at ORNL

SPRUCE

The Spruce and Peatland Responses Under Climatic and Environmental Change (SPRUCE) experiment assesses the response of northern peatland ecosystems to increases in temperature and exposures to elevated atmospheric CO2 concentrations.

USGS CSAS

USGS' Core Science Analytics, Synthesis, and Libraries (USGS CSAS ) synthesize and deliver Earth system data and information.

ORNL DAAC collaborates with USGS CSAS to build metadata editors and data discovery tools.

DataONE

DataONE provides access to multiple heterogeneous information collections through a centralized metadata registry and a distributed cyberinfrastucture.

ORNL DAAC is a member node within the DataONE network.

ORNL DAAC User Working Group

The DAAC's User Working Group (UWG) is an external advisory group, established by the Earth Observing System (EOS) Data Information System (EOSDIS) for the following purposes:

  • to assist in defining and accomplishing the DAAC's science goals;
  • to provide oversight and guidance on DAAC activities, including dataset acquisition, development of value-added products, user support, development activities, and operational functions;
  • to provide recommendations about annual work plans and long-term planning; and
  • to provide recommendations on interactions and agreements on data management between field campaigns and the ORNL DAAC.

The User Working Group meets once a year to review status and provide recommendations to the ORNL DAAC and NASA. UWG photograph from May 2015 meeting at ORNL. Additional information about the responsibilities of the UWG can be found in the ORNL DAAC UWG CharterPDF.

The User Working Group is interested in hearing from users on how to improve the DAAC and about datasets or model products the DAAC should pursue archiving.

To get further information about the User Working Group or to provide input to the DAAC or the User Working Group, please contact the DAAC scientist, Alison Boyer (boyerag@ornl.gov).
