Performance of the Australian Climate Ocean Model (AusCOM) and the Australian Community Climate and Earth System Simulator (ACCESS) Coupled Model in Simulating the World Ocean Climate

AusCOM is an IPCC-class global coupled ocean and sea ice model aimed to serve the Australian climate sciences community (including the Bureau of Meteorology, CSIRO and the Australian universities) for ocean climate research and applications. It comprises the NOAA/Geophysical Fluid Dynamics Laboratory Modular Ocean Model version 4.1 (GFDL MOM4p1), the Los Alamos National Laboratory Sea Ice Model version 4.0 (LANL CICE4.0), and a data atmospheric model (MATM). Numerical coupling utilises the Message Passing Interface within the PRISM_2-5 OASIS3 coupler. Recent multi-century experiments with international standard atmospheric forcing demonstrate that AusCOM has achieved a world class standard of performance in simulating the world ocean climate. A standard version is released as AusCOM1.0, an independent, self-contained, and easily setup package.

ACCESS is aimed to provide Australia with the next generation capability for weather prediction and climate/climate change simulation. The ACCESS coupled model is built by coupling the UK Met Office atmospheric model UM (Unified Model), and other sub-models as required, to AusCOM, under the same coupling framework. The ACCESS coupled model has been fully functional for 7 months and improvements have been made so that model skill scores for the recent century-length runs surpass those for the preceding CSIRO Mk3 model delivered to IPCC AR4. A range of CAWCR scientists are performing detailed testing to further improve the ACCESS model performance for the final AR5 version.
