[MITgcm-support] MITgcm diffusivities?

[Matthew Mazloff]

Hi Stephanie,

Yes, these are at all depths.  And they are likely based on some hand- 
wavy scaling arguments and effective diffusivity calculations.  As I'm  
sure you know, there are many processes a 1^o model does not resolve  
(e.g. internal waves) -- parameterizations are needed.  It's not  
obvious how to choose parameterization coefficients....
