ACCESS-NRI has taken on responsibility for ongoing support of ACCESS-OM2, so this repository is not being updated and will eventually be archived.
New ACCESS-OM2 experiments and code development should use the latest code release from ACCESS-NRI/ACCESS-OM2 and configurations from ACCESS-NRI/access-om2-configs, and all new issues should be posted on one of those repositories.
Standard configuration for 0.1 degree ACCESS-OM2 experiment (ACCESS-OM2-01) with JRA55-do 1 May 1990 - 30 April 1991 repeat-year forcing (RYF9091).
This is the physics-only version, on the master branch. For the version with BGC, use the master+bgc branch.
For usage instructions, see the ACCESS-OM2 wiki.
Run length and timestep are set in accessom2.nml. The configuration is supplied with a 300s timestep which is stable for a startup from rest, but very slow. After the model has equilibrated for a few months you should increase the timestep to 450s and then to 540s for improved throughput. You may even find it runs stably at 600s.
NOTE: All ACCESS-OM2 model components and configurations are undergoing continual improvement. We strongly recommend that you "watch" this repo (see button at top of screen; ask to be notified of all conversations) and also watch ACCESS-OM2, all the component models, and payu to be kept informed of updates, problems and bug fixes as they arise.
We request that users of this or other ACCESS-OM2 model code:
- consider citing Kiss et al. (2020) (http://doi.org/10.5194/gmd-13-401-2020)
- include an acknowledgement such as the following: The authors thank the Consortium for Ocean-Sea Ice Modelling in Australia (COSIMA; http://www.cosima.org.au) for making the ACCESS-OM2 suite of models available at https://github.com/COSIMA/access-om2.
- let us know of any publications which use these models or data so we can add them to our list.
