Dear Forum Members,
I have a experiment setup question that maybe someone will be able to help me with.
I want to run CAM coupled to an ocean mixed layer (SOM), however restore the SST values in some region (e.g. eastern tropical Pacific) back to values read from a data file.
Regarding this setup, I have three questions:
1) Which subroutine in the CESM code structure would be best to reset the SST field values in the subdomain, just before the next integration step? I want the model to use these prescribed values in the next time step to calculate the atmospheric response (e.g. wind, diabatic heating) instead of the calculated SOM values. I assume it would be overwriting the 'somtp' variable in the 'docn_comp_mod.F90' subroutine?
2) In which subroutine do I prescribe best the read routine for these boundary condition SST values? I assume the same place as the data ocean is normally read? I would like to read a new constant (value between 0 and 1 that defines the restoring region) that is defined on the same grid as e.g. the SST boundary conditions and make it available in the routine where I change the new SST value (e.g. docn_comp_mod.F90).
3) In the region where the CAM is coupled to the SOM using the prescribed climatological heat fluxes, what is the usual timescale set in the model for the anomaly restoring back to the climatological values and where would it be adjusted best?
Thank you very much in advance with any help and suggestions!
