Keywords

Tip

Global Change Master Directory (GCMD) Keywords are a hierarchical set of controlled Earth Science vocabularies that help ensure Earth science data, services, and variables are described in a consistent and comprehensive manner and allow for the precise searching of metadata and subsequent retrieval of data, services, and variables. Initiated over twenty years ago, GCMD Keywords are periodically analyzed for relevancy and will continue to be refined and expanded in response to user needs. The categories of GCMD Keywords are as follows.

  • Earth Science
  • Earth Science Services
  • Data Centers/Service Providers
  • Projects
  • Instruments/Sensors
  • Platforms/Sources
  • Locations
  • Horizontal Data Resolution
  • Vertical Data Resolution
  • Temporal Data Resolution
  • URL Content Types
  • Granule Data Formats
  • Measurement Names
  • Chronostratigraphic Units

    Tip

    Fast-Track Keywords:

    • An expedited review process (less than five business days) for proposed additions and changes that are small and have little or no impact on other users and metadata providers.

    Full-Review Keywords

    • The full review process for proposed GCMD keyword changes is a review process facilitated by the ESDIS Standards Coordination Office (ESO) with input from subject matter experts drawn from the user and provider communities. These reviews take longer (1-2 keyword releases a year) to complete and are used for GCMD keyword changes or changes that have a large impact on existing records and users.

    The keyword submitter will be notified whether their keyword is considered a fast-track or full review.
