Welcome to the NCI ESGF Node

The Earth System Grid Federation (ESGF) consists of federated data centres across the globe that enable access to the largest archive of climate data world-wide. This portal allows you to find, select and download data files from the federation.

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.

The EGSF is designed to integrate and interoperate with other software developed by the ESGF collaborators: such as NASA, NOAA, ESIP, and the European IS-ENES.

The NCI ESGF node currently hosts Australian produced data for the CMIP5, CMIP6, CORDEX, GeoMIP and PMIP3 data collections.

Additionally, we have locally replicated copies of data collections that have been published on other ESGF nodes.

Local Data Collections

Generally, data is publicly available for download and can be accessed without a login. However, some projects may require that you login first (you'll be prompted if this is required). If you've already created an account on another ESGF node then you can use that without needing to register again. Otherwise, you can register for a new account here. Additionally, some collections require registration as indicated in the table below.

Users with access to NCI systems such as Gadi or VDI can also access these collections on the global Lustre filesystem in the location(s) shown in the final column.

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. For model related questions, please find the modelling group contact information in the header of the NetCDF file.

For data management issues, please write the following to the 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,,,...
- 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


For more information on using the data please refer to the CMIP5 User Guide and CMIP6 User Guide.
