WELCOME TO THE GLOBAL CHANGE MASTER DIRECTORY
=============================================

NASA's GCMD holds descriptions of and access information for over
3,900 Earth science data sets. Areas covered include "atmosphere,
oceans, biosphere, hydrosphere, cryosphere, land surface, solid
earth, solar-terrestrial, and human dimensions of climate change."
Users can browse through the latest additions or search the
database using either fielded or free-text queries. Individual
descriptions are organized using the Directory Interchange Format
(DIF), a standardized set of fields containing attribute metadata
for each data set. Part of the mission of the GCMD is to provide a
place for data set holders to publicize their data. Online
registration uses the DIF Authoring Tool, which allows registrants
to insert metadata into DIF fields. GCMD's primary responsibility
is "software development and database population for the Committee
on Earth Observation Satellites International Directory
