The NASA Global Change Master Directory (GCMD) staff is pleased to announce the release of the GCMD keywords version 9.0. Version 9.0 consists of two new keyword schemes: (1) Measurement Name and (2) Granule Data Format.

The Measurement Name<> list is a preliminary set of (~100) keywords that represent an observable property, usually geophysical, geo-biophysical, physical, or chemical. The Granule Data Format<> list of keywords represent the format of the data that is distributed by the data center.

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 at<mailto:support at> or directed to Valerie Dixon at valerie.dixon at
