ready Global Change Master Directory Keywords

Abbreviation: GCMD Keywords


General Information
Global Change Master Directory (GCMD) Keywords are a hierarchical set of controlled Earth Science vocabularies that help ensure Earth Science data, services, and variables are described in a consistent and comprehensive manner and allow for the precise searching of metadata and subsequent retrieval of data, services, and variables. Initiated over twenty years ago, GCMD Keywords are periodically analyzed for relevancy and will continue to be refined and expanded in response to user needs.



Awaiting DOI assignment.

NOAA National Centers for Environmental Information Data Access Portal
The National Oceanic and Atmospheric Administration National Centers for Environmental Information (NOAA NCEI) Data Access Portal offers download and subsetting options for a growing collection of environmental data. While current offerings are primarily limited to weather and climate information, the application has a data-agnostic infrastructure designed to accommodate a broad spectrum of observation formats from across science disciplines.

NASA Global Change Master Directory / CEOS International Directory Network
The CEOS International Directory Network (IDN), working through NASA's Global Change Master Directory (GCMD), holds more than 32,000 Earth science data set descriptions, which cover subject areas within the Earth and environmental sciences. The project mission is to assist researchers, policy makers, and the public in the discovery of and access to data, related services, and ancillary information (which includes descriptions of instruments and platforms) relevant to global change and Earth science research. The GCMD/IDN is an international effort developed to assist researchers in locating information on available data sets. The directory provides free, online access to information for scientific data worldwide in the Earth sciences: geoscience, hydrosphere, biosphere, satellite remote sensing, and atmospheric sciences. Sometimes referred to as the CEOS IDN Master Directory, it describes data held by university departments, government agencies, international government agencies, and associated organizations. Both GCMD and IDN are used to refer to this repository in help pages and other websites, and therefore both are represented here.

NERC British Oceanographic Data Centre Data Archive
BODC makes available biological, chemical, physical and geophysical data on the marine environment.

Environmental Data Portal
EnviDat is the environmental data portal and repository developed by the Swiss Federal Research Institute WSL. The portal provides unified and managed access to environmental monitoring and research data. The portal has the capability to host and publish data sets. While sharing of data is centrally facilitated, data management remains decentralised and the know-how and responsibility to curate research data remains with the original data providers.
