We will be performing system maintenance on Wednesday, January 25th at 1 PM MDT.

We are expecting this work to take less than a day. Sorry for any inconvenience caused.

About the Earth System Grid

The Earth System Grid Federation (ESGF) is an international collaboration with a current focus on serving the World Climate Research Programme's (WCRP) Coupled Model Intercomparison Project (CMIP) and supporting climate and environmental science in general. The ESGF grew out of the larger Global Organization for Earth System Science Portals (GO-ESSP) community, and reflects a broad array of contributions from the collaborating partners listed below.

This web site is a Gateway to scientific data collections, which may be hosted at sites around the globe. Gateways are web portals that allow you to register for access and discover data, and they work in conjunction with Data Nodes, which host data collections and provide services. Once registered at a Gateway, you have potential access to the entire ESGF network of Gateways and Data Nodes.

The U.S. Earth System Grid Center for Enabling Technologies (ESG-CET) project is a primary contributor of cyberinfrastructure for the ESGF effort, especially the gateways and nodes described above. ESG-CET's primary sponsor is the Department of Energy's Scientific Discovery through Advanced Computing program (SciDAC2), with co-sponsorship by the U.S. National Science Foundation (NSF).

The Gateway effort, led by the The National Center for Atmospheric Research (NCAR), reflects important contributions from several sponsors. In addition to ESG-CET, the U.S. NSF contributed substantially to its development through NCAR's core program, the Cooperative Arctic Data and Information Service (CADIS), and the NSF TeraGrid Science Gateways program.

The Earth System Curator project has led an effort to radically advance the richness of model metadata and the integration of simulations and data in the gateway. Currently sponsored by NOAA's Global Interoperability Program (GIP), Curator has also been generously supported by NSF and NASA.

The Curator team collaborated closely with the EU METAFOR (Common Metadata for Climate Modelling Digital Repositories) project, which developed the Common Information Model (CIM) and related technologies. METAFOR is sponsored by the EU Framework Programme 7 (FP7).
