A new version of the Australian Community Climate and Earth System Simulator coupled model, ACCESS-CM2, has been developed at CSIRO for a wide range of climate modelling research and applications. In particular, ACCESS-CM2 is one of Australia’s contributions to the World Climate Research Programme’s Coupled Model Intercomparison Project Phase 6 (CMIP6). Compared to the ACCESS1.3 model used for CMIP5 submission, all model components have been upgraded as well as the coupling framework (OASIS3-MCT) and experiment control system (Rose/Cylc). The component models are: UM GA7.1 for the atmosphere, CABLE2.5 for the land surface, MOM5 for the ocean, and CICE5.1.2 for the sea ice. 

This talk presents a selection of variables from the ACCESS-CM2 CMIP6 historical experiments in terms of global pattern, (global mean) temporal evolution in comparison against the observation, results of ACCESS1.3 for CMIP5, and results from other CMIP6 models available on ESGF, as part of assessment of the model performance in climate change simulation. The selected variables include the surface temperature, precipitation, sea ice, and ocean circulations.
