The NASA Global Change Master Directory (GCMD) staff is pleased to announce the release of the GCMD keywords version 14.0. Version 14.0 of the keywords consists of new Machine Learning Models and Training Data keywords and other keywords added from the community. The Machine Learning Models and Training Data keyword changes were requested by the Radiant Earth Foundation and based on a community review conducted through NASA's Earth Science Data and Information Systems (ESDIS) Standards Coordination Office (ESCO). Based on the review, there were 28 new keywords added. Since these keywords are new, there is no user impact.

Please find below a table of the keywords. Please post any questions about this release to the GCMD Keyword Forum. The keywords help facilitate the classification and discovery of Earth Science data by providing a rich vocabulary for characterizing the data. The GCMD keywords are used by hundreds of data providers worldwide for categorizing the ~33,000 records stored in the Common Metadata Repository

For more information about the keywords and how to access them, please visit the Keyword Landing Page. Questions about the keywords can be submitted to support@earthdata.nasa.gov or directed to Valerie Dixon at valerie.dixon@nasa.gov.
