Hiya. Yes, that is a way to do a restart from an existing run, using the same version of ACCESS-OM2. But the code has moved a long way from that original RYF run, which started in about 2019! Others will know more, but I think it will be difficult to use those restart files to run with the new ACCESS-NRI release of OM2. One option may be to take the T/S from the restart file to create a new initial condition file and run it from there? [It will be close to spun up, but may need a few years to get stable.]
We have been considering for some time whether we should rerun the RYF control, and have concluded that the use case may not be so urgent (and we definitely don’t have the spare CPU time this quarter).
