Welcome to the DKRZ ESGF-CoG Node

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.

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. Visit the ESGF page to get an insight into our design and mission.

This is the portal hosted by the German Climate Computing Centre (DKRZ). As a national HPC center, DKRZ provides high performance computers, high capacity data storage and data management for German climate research. In addition DKRZ’s specialists offer a range of services and support covering modeling and programming as well as data dissemination and long-term archival.

            

New server side processing capabilities  

DKRZ is part of the European IS-ENES Infrastructure. New services are developed within the project to provide users with server-side processing capabilities. It means your analyses can be performed near the data at the IS-ENES HPC centers and you will download the results of your analyses and avoid the heavy data download of raw model data. This is especially beneficial for users with low network bandwidth or limited access to high performance facilities.

    Please visit our new server-side services:
  • 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.

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. If you do not find what you are looking for, please write to the modelling group, the contact information is in the header of the NetCDF file.

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

- Your browser and operating sytem, 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, esgf-index1.ceda.ac.uk, esgf-node.llnl.gov,...
- The steps required to reproduce the problem
- The exact error message. Run the script in debug mode to get a detailed error message: $ bash wget-xxx.sh -H -d
