Program Components

ESDS achieves its vision of making NASA’s free and open Earth science data interactive, interoperable, and accessible for research and societal benefit today and tomorrow through various components.

Data System Evolution and Competitive Programs

The Data System Evolution (DSE) element of ESDS funds various research opportunities, as well as interagency initiatives and promotion of data and service interoperability through development and implementation of standards. DSE is composed of two competitive components: Advancing Collaborative Connections for Earth System Science (ACCESS) and Citizen Science for Earth Systems Program (CSESP). DSE also supports the Interagency Implementation and Advance Concepts Team (IMPACT) activity, and the development of long-term data records needed by NASA scientists.

  • Competitive Programs
  • Earth Science Data Systems Geographic Information Systems Team (EGIST)
    EGIST serves as the subject matter expert for geographical information systems (GIS) to ESDS program components, provides guidance, evaluates GIS technology and engages the community in developing program-wide strategy.
  • Interagency Implementation and Advanced Concepts Team (IMPACT)
    IMPACT builds partnerships with other Federal agencies, the applications community, decision makers, non-governmental organizations, and other organizations to encourage the adoption of NASA Earth observation data into their workflows and operational models.
  • Science Tools and Portals
    Science portals comprehensively address and communicate information about a specific scientific topic in collaboration with research and analysis programs. The Sea Level Change portal provides access to data, analysis tools, and simulations of glaciers, ice sheets, sea level, and the solid Earth.

Earth Observing System Data and Information System (EOSDIS)

EOSDIS ingests, processes, archives, and distributes data from NASA’s fleet of Earth-observing satellites and provides end-to-end capabilities for managing NASA’s Earth science data from diverse sources - satellites, aircraft, field measurements, and various other programs.

EOSDIS is managed by the Earth Science Data and Information System (ESDIS) Project and includes the following activities and products:

  • Science Investigator-led Processing Systems (SIPS)
    Most of the Earth Observing System (EOS) standard products are produced at facilities under the direct control of the instrument Principal Investigators/Team Leaders (PIs/TLs) or their designees.
  • Distributed Active Archive Centers (DAACs)
    EOSDIS is designed as a distributed system. The DAACs - located throughout the United States - process, archive, document, and distribute data from NASA's past and current Earth-observing satellites and field measurement programs.
  • Core System Components
    EOSDIS core components support users across all DAACs, and include the Common Metadata Repository Global Imagery Browse Services, Worldview, metrics and Earthdata Login.
  • Land, Atmosphere Near real-time Capability for Earth Observing System (LANCE)
    LANCE provides access to near real-time products from the Atmospheric Infrared Sounder (AIRS), Advanced Microwave Scanning Radiometer 2 (AMSR2), Microwave Limb Sounder (MLS), Moderate Resolution Imaging Spectroradiometer (MODIS), Measurement of Pollution in the Troposphere (MOPITT), Ozone Monitoring Instrument (OMI), Ozone Mapping Profiler Suite (OMPS) and Visible Infrared Imaging Radiometer Suite (VIIRS, including VIIRS Land and VIIRS Atmosphere) instruments. Products are available within 3 hours from observation.

Earth Science Data System Working Groups (ESDSWG)

ESDSWG focuses on the exploration and development of recommendations derived from pertinent community insights of NASA's heterogeneous and distributed Earth science data systems.

Small Satellite Commercial Data Buy Program

In the fall of 2018 NASA initiated the Small Satellite Commercial Data Buy Program to evaluate how observations from Earth-orbiting, small-satellite constellations can be a cost-effective means to augment observations from established Earth science missions.

Standards and Interoperability Coordination and Development

NASA's ESDIS Standards Office (ESO) assists in formulating standards policy, coordinates standards activities within ESDIS, and provides technical expertise and assistance with standards related tasks within NASA's ESDSWG.

ESO conducts reviews of proposed standards, practices, and technical information relevant to the ESDIS Project mission. Documents are reviewed as part of the ESDIS standards process. Approved documents are published and listed on the Standards and Requirements page, along with related technical information and useful ESDS references. ESO also leads the ESO Standards Interest Group (SIG) to facilitate discussion about data systems standards, conventions, and best practices relevant to NASA's EOSDIS.
