Hi Spencer, thanks so much for the info.
Re the MOM5 restarts, I did not end up interpolating anything, as I only realised in hindsight that the 1 degree ACCESS-OM2 also has 50 vertical levels - i.e. by my understanding, the same grid as ACCESS ESM1.5. Thus I just added the line below to the config.yaml file, and I’m not sure where the error came from if I did not modify the restart files?
restart:
