Hi @katner99,
I’ve had a look at the warm start scripts from GitHub - coecms/esm-historical, and it does look like the only changes we need are to adjust the way the sea ice restarts are handled.
I’ve uploaded a version of the scripts with some quick changes to a gist here, which are currently working when branching off the PI-02 simulation in /g/data/p73.
I’ll outline the main changes in case any of the details are useful!
As mentioned in the previous topics here, ESM1.5 no longer uses the timing information given by the variables init_data and initdate from the <control-directory>/ice/input_ice.nml file, instead reading them from a new file restart_date.nml placed in the restart directory.
Likewise, the runtime0 and runtime variables from the <restart-directory>/ice/input_ice.nml are no longer used.
As a result the parts of the warm start scripts which set these variables can be removed. These include the three sections here, here, and here which I’ve either deleted or commented out in the updated version.
The final step is to make the new restart_date.nml file to carry the new timing information, which is added here.
Let me know if you have any questions about the changes to the scripts, or any issues with running them!
