Welcome to the DKRZ ESGF-CoG Node

Please try our updated ESGF web application (named "Metagrid"), now undergoing beta testing. For this test release we are reaching out for help from users in the community to report any issues they encounter with the application. The beta-test web application can be found at the following site:

Please see the following page for more information including a FAQ:

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 Intercomparison Project CMIP. The WGCM Infrastructure Panel is the official CMIP document home. See a CMIP intro video here.

This portal is an interface for users to access model data that are distributed in several data centers, also called data nodes. The portal itself does not host any data. This is the portal hosted by the German Climate Computing Centre (DKRZ).
New server side processing capabilities  

                             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.

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 emailing list:

- Your browser and operating system, e.g. Firefox 68.0.2 on Ubuntu 18.04
- Your OpenID
- The complete name of the file(s) or data set(s) you attempt to download
- The host node, for instance,,,...
- The steps required to reproduce the problem
- The exact error message. Run the script in debug mode to get a detailed error message: $ bash -H -d

Please note:

  • Access to the THREDDS catalogs is disabled on several data nodes due to performance issues
  • Access to "My Profil" is disabled due to privacy issues
