Welcome to the DKRZ ESGF-CoG Node

--> User Tutorial and FAQs.

The Earth System Grid Federation (ESGF) maintains a global system of federated data centers that allow access to the largest archive of model climate data world-wide. ESGF portals like this one provide access to the output of the climate models contributing to the next assessment report of the Intergovernmental Panel on Climate Change IPCC through the Coupled Model Intercomparion Project CMIP. The WGCM Infrastructure Panel is the official CMIP document home. See a CMIP intro video here.

                             Tired of downloading tons of model data?                                    Would you like free computing resources to analise CMIP big data?

The infrastructure of the European part of ESGF is coordinated within the IS-ENES project and new services are developed to provide users with server-side processing capabilities. It means your analyses can be performed near the data at the IS-ENES HPC centers to avoid the heavy data download of raw model data. Our new server-side services:

• the European Network of Earth System Modelling Climate Analyitics Service (ECAS).
• the Analysis Platforms open call for multimodel analyses of the CMIP6 and CORDEX model data and apply for CPU computing hours at the IS-ENES HPC centers with direct access to locally maintaned high volume data sets
• the Climate4Impact portal dedicated to climate impact users who want to perform server-side visualizations, indices calculations, downscaling, subsetting, and regridding, and download the lightweight results of their analyses.

The following projects require a ESGF account (create account). Some also require a Group Registration to access their data (see links below).

If you do not find want you are looking for, enable 'Show All Replicas' in the faceted search engine to increase the chances of finding a suitable federated node in the grid that hosts the data of your interest. Please, visit the Data Nodes Status to find the nodes that are down.

Learn the full capabilities of the ESGF service by visiting the User Tutorial and FAQs.

Find the model documentation at the Earth System Documentation ES-DOC portal. As part of the ES-DOC ecosystem, the Errata Service centralizes timely information about known issues of ESGF data. Look up an issue here. If the errata you found is not there, please write to the modelling group, the contact information is in the header of the NetCDF file. For CMIP6 data, click on "Show Citation" when finding the data in the faceted search.

For data management issues, please write the following to the esgf-user@lists.llnl.gov emailing list:
