ACCESS submission to CMIP6

By August 20th, 2019

CMIP6 Details

The objective of the Coupled Model Intercomparison Project (CMIP) is to better understand past, present and future climate changes arising from natural, unforced variability or in response to changes in radiative forcing in a multi-model context.

For more information, see ACCESS CMIP6 Public Wiki.

ACCESS Submission to CMIP6

We are submitting climate simulations from our two AOGCM versions of ACCESS: CM2 and ESM1.5.

In addition to the required DECK and historical simulations, we will be submitting to the following MIPs:

  • CM2: FAFMIP, RFMIP, ScenarioMIP, DAMIP, SIMIP
  • ESM1.5: C4MIP, CDRMIP, RFMIP, ScenarioMIP, DAMIP, CovidMIP, PMIP, LUMIP
  • Additionally, the COSIMA (Consortium for Ocean-Sea Ice Modelling in Australia) group will be submitting data to OMIP from two ocean/sea-ice only models, ACCESS-OM2 (1°) and ACCESS-OM2-025 (0.25°). For more information, see http://cosima.org.au/index.php/models/access-om2/.

For the current status of our CMIP6 experiments and submissions: CM2 status, ESM1.5 status, and OM2(-025) status.

CMIP6 Output (data, errata and papers)

Data (CMIP6-compliant; ‘CMORised’):
CMIP6 data are available through the following portals:

  • NCI: Complete ACCESS data can be accessed through the project fs38 (located at /g/data/fs38/publications), while the NCI replication node (for non-ACCESS models) can be accessed though project oi10 (located at /g/data/oi10/replicas). These projects can be joined via the NCI Mancini portal.
  • ESGF: The Earth System Grid Federation is a collaboration that supports CMIP activities and operate data and metadata facilities to enable the storage and analysis of CMIP6 data through several nodes, which can be searched for relevant datasets through an online interface.

Data (Model Output):

Model output from all CMIP6 production runs is available on NCI through the project p73 (/g/data/p73/archive/CMIP6). This data is semi-processed (i.e. UM output converted to netCDF4), and is not compliant with CF conventions. Details for each dataset can be found at the ACCESS Model Output Wiki.

Errata:

Errata documentation for following retracted CMIP data, which includes ACCESS models (filtered through the ‘Source ID’ drop down).

Publications:

A list of relevant research papers and publications; including those focusing on ACCESS data, and multi-model analyses that include ACCESS models.

Citations:

If you are using ACCESS data in a publication, please cite the relevant DOIs. A list of all CMIP6 MIP-level DOIs, including all ACCESS submissions, can be found here.

A sample of results from CMIP6 simulations with ACCESS models:

Global surface temperature anomalies (relative to 1850-1900) for the CMIP6 historical period, as simulated by ACCESS-CM2 (blue; fine lines represent ensemble members), with observations in black from HadCRUT4.

Global surface temperature anomalies (relative to 1850-1900) for the CMIP6 historical period with Tier 1 DAMIP simulations, as simulated by ACCESS-CM2 (fine lines represent ensemble members), with observations in black from HadCRUT4.

Global surface temperature anomalies (relative to 1850-1900) for the CMIP6 historical period and four main future scenarios, as simulated by ACCESS-CM2 (solid lines) and ACCESS-ESM1.5 (dashed lines).

Australian average surface temperature anomalies (relative to 1961-1990) for the four main future scenarios (with the end of CMIP6 historical period; observations in black), as simulated by ACCESS-CM2 (thick lines) and ACCESS-ESM1.5 (thin lines).

Global surface temperature anomalies (relative to 1850-1900) over the 2020-2050 period for the ScenarioMIP experiment ‘ssp245’ and the CovidMIP (officially DAMIP) experiments ‘ssp245-cov-strgreen’ and ‘ssp245-cov-modgreen’, as simulated by ACCESS-ESM1.5 (fine lines represent ensemble members).
