ACCESS-OM2 is a global coupled ocean - sea ice model. It is being developed by COSIMA. ACCESS-OM2 builds on the ACCESS-OM (Bi et al., 2013) and AusCOM (Roberts et al., 2007; Bi and Marsland, 2010) models originally developed at CSIRO.
ACCESS-OM2 consists of the MOM 5.1 ocean model, CICE 5.1.2 sea ice model, and a file-based atmosphere called YATM coupled together using the OASIS3-MCT v2.0 coupler. Regridding is done using ESMF and KDTREE2.
ACCESS-OM2 comes with a number of standard configurations. These include sea ice and ocean at 1.0, 0.25 and 0.1 degree horizontal grid spacing forced by JRA-55-do and CORE2 atmospheric reanalyses.
The JRA55-do model configurations and performance are described in Kiss et al. (2019), with further details in the ACCESS-OM2 technical report.
Model output can be accessed by NCI users via the COSIMA Cookbook.
For information on downloading and running the model, see the ACCESS-OM2 wiki.
Requests for help and other issues associated with the model, tools or configurations can be registered as ACCESS-OM2 issues.
