Tracers in ACCESS-OM3

@angus-g’s PR has been merged. It may be a little while before we do another ACCESS-OM3 release, so I’ve created a “prerelease” that you can use in the meantime. You can use this by making the following changes to your config.yaml:

...

#Model software version
modules:
    use:
        - /g/data/vk83/modules
+       - /g/data/vk83/prerelease/modules
    load:
-       - access-om3/2026.05.002
+       - access-om3/pr257-1
        - model-tools/mppnccombine-fast/2025.07.000

...

manifest:
  reproduce:
-   exe: True
+   exe: False

...

Add the following to your MOM_input to prevent the accumulation of tracers with USE_FILE_DYES:

FILE_DYE_TRACERS_ACCUMULATE = False
