[MITgcm-support] geostrophic velocity in the model

[Martin Losch]

Dimitris,

I have once written a matlab function that computes geostrophic thermal 
wind starting form the surface elevatation. But I implicitly assume 
that the surface elevation is all geostrophic, regardless of scales or 
anything else. I can provide you with this function, you'll have to 
adjust a little bit though.
