NASA’s Global Change Master Directory (GCMD)
The Global Change Master Directory (GCMD) enables users to locate and obtain access to Earth science data sets and services relevant to global change and Earth science research.
GCMD also maintains a DIF portal (portals are views; subsets) and a SERF portal representing the subset of ESIP data within the GCMD database.
