[Mitgcm-support] horizontal viscosity

[mitgcm-support at dev.mitgcm.org]

Hi,

are there any plans to replace the so-far constant horizontal 
viscosities, viscAh and viscA4, by 2D or 3D fields? So that one could 
e.g., scale the coefficients with variable grid size, or implement 
something like a Smagorinski-type viscosity? If I were to code this up, 
would it make sense to go for (global) 2D fields Ah(i,j,bi,bj) or should 
I immediately introduce 3D fields Ah(i,j,k,bi,bj)? Is this anything of 
interest to anyone else or is it just me (in which case I would do as I 
please and not check anything in (o: )?

Martin
