ACCESS-OM stands for ACCESS Ocean Model. There is more than just an ocean model, but it indicates that this is not a fully-coupled model, i.e. not coupled with a model atmosphere, the atmospheric fields that drive the model are provided by a data product, usually derived from reanalysis.

ACCESS-NRI will release an ACCESS-OM model configuration. The first release of ACCESS-OM will be derived from the COSIMA ACCESS-OM2 suite and will include ocean and sea ice components.

ACCESS-OM2 1 is a suite of coupled ocean-sea ice models developed by the Consortium for Ocean-Sea Ice Modelling in Australia (COSIMA). All models use the MOM5 ocean model coupled to the CICE5 sea ice model via OASIS3-MCT.

The models in the ACCESS-OM2 suite differ by their grid spatial resolution:
