[MITgcm-support] rbcs diagnostics

[Christopher L. P. Wolfe]

Renske,

RBCS doesn’t have diagnostic output by default. Since the relaxation terms are linear in both the relaxation target and the dynamical variable, you can easily construct the appropriate term from other diagnostic output. For debug purposes, it can be nice to have direct diagnostics output to check that the relaxation terms are what you think they are. I’ve attached to modified files from the RBCS package that create diagnostics for the temperature and salinity tendency due to RBCS. They’re based on checkpoint64d, but you can easily copy them over to whatever checkpoint you’re using.

Cheers,
Christopher

I cannot find anything in the manual or in the package code, and the only thing I could find in the support database is that apparently Um_Ext and Vm_Ext already include the RBCS part. Is the T/S part diagnosed anywhere? I can of course add a diagnostic, but I would like to make sure it is not included somewhere else before I start.
