Climate simulation without SST variable

[janac4]

Hi everyone,
I'm currently trying to run a WRF simulation using CMIP6 data. Unfortunately, the input data I want to use doesn't have neither skin temperature other SST variable (usually called 'ts' and 'tos' in CMIP6 files).
Because of that I can't use sst_update in namelist.input, right?
Is it physically appropiate to run a 30 year simulation without this files in input data? How does the model work in this case (where does the SST variable come from)?
I thought that maybe real.exe would crash but it worked fine. However, when running wrf.exe, I am encountering CFL errors from the beginning, could this error be related to SST variable?

I attached my current namelist.input in case someone can give me an advice on how to manage wrf.exe.

Apologies for the long delay in response while our team tended to time-sensitive obligations. Thank you for your patience.

For a long simulation, you probably should use some sort of higher-resolution sst fields. If the input data you're using don't include them, it's okay to obtain them elsewhere and to use them with the other atmospheric data. To do that, you can follow the procedures described here.
