The International Center for Global Earth Models collects and distributes historical and actual global gravity field models of the Earth and offers calculation service for derived quantities. In particular the tasks include: collecting and archiving of all existing global gravity field models, web interface for getting access to global gravity field models, web based visualization of the gravity field models their differences and their time variation, web based service for calculating different functionals of the gravity field models, web site for tutorials on spherical harmonics and the theory of the calculation service. As new service since 2016, ICGEM is providing a Digital Object Identifier (DOI) for the data set of the model (the coefficients).

The CEOS International Directory Network (IDN) home page and search portal serve as NASA's contribution to the Committee on Earth Observation Satellites (CEOS). IDN's mission is to assist researchers, policy makers, and the public in the discovery of and access to data relevant to global change and Earth science research. The Draft Metadata Management Tool (DMMT) is a metadata authoring tool that IDN contributors can use to propose new or modified CMR records.
