Australian published CMIP related datasets fall under both the CMIP5-era and CMIP6-era projects. In addition, NCI has committed to replicating key internationally published CMIP output locally, along with providing key observational and reanalysis datasets. For further information on the different climate datasets and available variables see the Datasets and Available Variables page.
This page provides details of the access options available to users to search and access the CMIP data available at NCI. Sections in this page are broken into the following topics:

Access to the CMIP and related data available is available via three key methods:
Detailed training on each of the access options may be found under the Training page.
Primary access to the CMIP data, from both raijin and the VDI, is achieved via requesting to join the relevant project space and accessing the data from /g/data/<project> (see table below).
Request to Access a Data CollectionYou may request to join a data collection through my.nci.org.au/mancini. Your request will then be sent to the data collection manager for approval. You must agree to the same Terms and Conditions that govern access to the data via the Earth Systems Grid Federation: |

CMIP6 Published and Official Replica DataAll CMIP6 data will fall under the standard data reference syntax (DRS) defined by the ESGF (for more information see: https://www.earthsystemcog.org/site_media/projects/wip/CMIP6_global_attributes_filenames_CVs_v6.2.6.pdf), sorting the data into the following directory format: CMIP6/CMIP/<institution_id>/<source_id>/<experiment_id>/<member_id>/<table_id>/<variable>/<grid_label>/<version> CMIP5 Australian Published and Official Replica DataThe CMIP5 published data (project code = rr3) and official replica data (project code = al33) can be found with the following directory structure: /g/data/<project>/publications/CMIP5/output1/<institute>/<model>/<experiment>/<frequency>/<realm>/<table>/<ensemble>/<version><variable> The above directory format conforms to the official DRS defined by the ESGF (see https://cmip.llnl.gov/cmip5/docs/cmip5_data_reference_syntax_v1-00_clean.pdf for more information.) Note some of the key difference in the facets between CMIP5 and CMIP6, in particular "model" in CMIP5 has become "source_id" and "ensemble" has become "member_id". Other facets have similar names, though in CMIP6 the convention often includes an "_id". CMIP5 Unofficial Replica DataFor historical reasons the currently available "unofficial" replica data in ua6 is organised with the following structure: /g/data/ua6/DRSv2/CMIP5/<model>/<experiment>/<frequency>/<realm>/<ensemble>/<variable>/latest Note that this data is not the official replica and is planned to be progressively decommissioned over time.
