[MITgcm-support] Time stepping for momentum and tracers

[Uchida Takaya]

Dear MITgcm support,

In the data namelist file, there is an option to set the time stepping for momentum (deltaTmom) and tracers (deltaTtracer) separately. 
Ideally, they would have the same values but due to computational constraints, I would like to loosen the tracer time stepping if possible.
Is there a best practice for this, e.g. ratio between deltaTmom and deltaTtracer etc.,  or should they not have different values at all?

Thank you,
Takaya
