New configurations
ACCESS-NRI has released new versions of the global 1°, 0.25° and 0.1° physics-only configurations. The biogeochemical configurations have not been updated. Key changes in the new releases are:
All configurations
- Update to a new version of MOM5 that allows using ACCESS-OM2 with coupled generic-tracers, including WOMBATlite/mid.
- Update from Intel Classic to oneAPI compilers.
1° and 0.1° configurations only
- Fixes to the CICE grid. These fixes were already included in version 2.0 of the 0.25° configurations.
Details of the releases, including a full list of changes, are here:
What version are these released configurations?
The released configurations are version 3.0 indicating that they are not bitwise reproducible with their previous versions (version 2.0). Specifically, the changes to the CICE grid and compiler updates do not preserve answers.
