ACCESS-OM3 Experiments
The below lists key experiments that are being used to improve, evaluate and drive development for OM3. We welcome scientific and technical feedback on these runs. If you would like to get involved in evaluation of these runs, see instructions here and an overview here.
As these data are from beta releases of configurations, they will not be kept long-term and will be deleted when newer control experiments are completed.
This data, and the configurations they are based on, are licensed by CC-by-4.0 and therefore can be freely shared, distributed and modified. Users of ACCESS-NRI models, data, tools or expert support are required to clearly include an acknowledgement in all publications/reports/public releases.

Community run sensitivity tests
The following are additional sensitivity-test experiments, exploring specific parameter choices rather than serving as control experiments. As these experiments are for specific interests, we don't track the same level of detail for these runs, but evaluation figures, base configuration, model build, run length and the ESM datastore path are available where practical.
