Hi @huazhen,
Apologies for the delay in getting back to you on this!
I’ve had a further look into suite u-dl308. My understanding is that the file temp_sfc_restore.nc file is used to specify restoring surface temperatures, for example in pacemaker experiments. When the MOM5 settings (in app/mom/rose-app.conf) contain
temp_restore_tscale=x
where x>0, the model will try and read this file, and produce the above error if it is missing. It looks like the update_sst task is responsible for copying this file to the right place, and so when UPDATE_SST=false, the model fails to find it.
If you would like to run this suite with UPDATE_SST=false, it might be necessary to deactivate the temperature restoring, by setting
temp_restore_tscale=-1
which matches the pre-industrial suite u-cy339.
Let me know if you have any questions or run into any issues!
Cheers,
Spencer
