Ocean/sea ice Model (ACCESS-OM)

ACCESS-OM2 is the ocean and sea-ice component of the ACCESS coupled model. ACCESS-OM2 provides the Australian climate community with ocean weather and climate research, including seasonal forecasting, climate variability studies, downscaling of climate in the marine environment around Australia, and ocean biogeochemistry modelling.

ACCESS-OM2 is an Earth System model configuration that links the Modular Ocean Model (MOM), the sea-ice model (CICE), a file-based atmosphere called YATM (Yet Another Atmospheric Model) and the Ocean-Biogeochemistry Model (WOMBAT), coupled together using the OASIS coupler.

ACCESS-OM2 has been developed by Consortium for Ocean-Sea Ice Modelling in Australia (COSIMA) in collaboration with the Geophysical Fluid Dynamics Laboratory (for an ocean model component), the Los Alamos National Laboratory (for a sea-ice model component), and the European Centre Centre Européen de Recherche et de Formation Avancée en Calcul Scientifique (CERFACS) (for an atmosphere­-ocean OASIS3-MCT coupler).

Acknowledging the use of ACCESS-OM2

Users of ACCESS-NRI models, data, tools of expert support are required to clearly include an acknowledgement in all publications/reports/public releases. Correct acknowledgement allows us to demonstrate our impact, find how our infrastructure is being used, and increase recognition of value of the ACCESS National Research Infrastructure. We suggest to use the following statement:

“This research used the ACCESS-NRI’s model ACCESS-OM2, which is enabled by the Australian Government’s National Collaborative Research Infrastructure Strategy (NCRIS)”

ACCESS-NRI modelling relies on computational and data resources operated by Australia’s National Computational Infrastructure (NCI). ACCESS-NRI and NCI are enabled by the Australian Government, Department of Education, through the National Collaborative Research Infrastructure Strategy (NCRIS)

ACCESS-OM2 Components

How is ACCESS-OM2 used?

ACCESS OM2 is used as the ocean-sea ice component for the OMIP component of the Coupled Model Inter-comparison Project (CMIP). ACCESS-OM2 is designed to be consistent with the fully coupled version of ACCESS (CM2).
