This page lists the COSIMA “FlagshipModel Configurations”, along with links to information on the model configurations, code bases, publications and who to contact for more information.

ACCESS-OM2

ACCESS is the Australian community climate model. The ocean model components of ACCESS include MOM5.1, with the CICE5 sea ice model and OASIS-MCT coupling. ACCESS-OM2 is designed to be consistent with the full coupled version of ACCESS (to be released shortly as ACCESS-CM2). COSIMA supports ACCESS-OM2 at three resolutions: the standard 1° resolution, and the higher 0.25° and 0.1° resolutions. Each resolution is defined at the Equator, with a tripolar grid in the north and Mercator projection down to 65°S. The entire ACCESS-OM2 suite is available from our OceansAus GitHub repository (currently still in pre-release mode). Details of each model are listed below.

ACCESS-OM

ACCESS-OM2 is the moniker used to describe the suite of ACCESS Ocean Models, as well as specifically the
default 1° model version, with 50 vertical levels. The model is configured to run with both the CORE and JRA55-do forcing datasets. Read More ..

ACCESS-OM2-025

ACCESS-OM2-025 is the 1/4° resolution ACCESS-based ocean-sea ice model, with 50 vertical levels.  The model is configured to run with the JRA55-do forcing dataset. Read more …

ACCESS-OM2-01

ACCESS-OM2-01 is a newer 1/10° ocean-sea ice model. It uses MOM5.1 with 0.1° lateral resolution at the Equator, tripolar in the north and Mercator projection down to 65°S, with 75 vertical levels. The sea ice is CICE5.1, coupled with the OASIS3-MCT coupler. The model is configured to run with the JRA55-do forcing dataset. Read more …

MOM-SIS

Much of the ocean-sea ice modelling research in Australia in the last two decades has used the Modular Ocean Model, known as MOM. MOM is derived from NOAA’s Geophysical Fluid Dynamics Laboratory in Princeton, and has a worldwide user base. It comes pre-packaged with the FMS coupler and the SIS sea ice model. There are COSIMA configurations of MOM at both 0.25° and 0.1°, including biogeochemistry. Each of these model options is detailed below.

MOM-SIS-025

MOM-SIS-025 is our workhorse 1/4° ocean-sea ice model. It uses MOM5.1 with 0.25° lateral resolution at the Equator, tripolar in the north and Mercator projection down to 65°S, with 50 vertical levels. The sea ice is SIS, coupled with the FMS coupler. The model can be forced using either CORE or JRA forcing sets. The model has been used in a wide range perturbation experiments and publications. Read more …

MOM-SIS-01

MOM-SIS-01 is our 1/10° ocean-sea ice model. It uses MOM5.1 with 0.1° lateral resolution at the Equator, tripolar in the north and Mercator projection down to 65°S and 75 vertical levels. The sea ice is SIS, coupled with the FMS coupler. The model can be forced using either CORE or JRA forcing sets. The model has been used in a range perturbation experiments and publications.

MOM-SIS-025-WOMBAT

MOM025-FMS-SIS-WOMBAT is our workhorse 1/4° ocean-sea ice model coupled to the WOMBAT biogeochemistry model. It uses MOM5.1 with 0.25° lateral resolution at the Equator, tripolar in the north and Mercator projection down to 65°S, with 50 vertical levels. The sea ice is SIS, coupled with the FMS coupler. The model can be forced using either CORE or JRA forcing sets. The model undergone substantially tunings to improve the tracer distributions. Read more …
