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

```auto
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

```auto
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
