GCMD Keywords
One of the organizing tools employed within GDEX is the use of Global Change Master Directory (GCMD) Keywords. This set of hierarchical keywords is well-established in the Earth Science community. The following two keywords have been added by NASA Earth Data to the GCMD database:
- In the file format category: obs_seq => observation sequence file
- In the project category: NSF NCAR/DART => Data Assimilation Research Testbed
These keywords can be used to tag DART related datasets in GDEX.
