[MITgcm-support] KPP and zref with fine resolution vertical grid

[Dimitris Menemenlis]

No experience with AMPS but my guess is that your problem is that your model subgrid-scale physics and other parameters, e.g., albedo were adjusted for different forcing and are not consistent with AMPS.

If you suspect KPP as primary cause, you could try running with one of the other vertical mixing schemes, e.g., pkg/ggl90. But I doubt that's your order-1 problem. I don't recommend modifying KPP code as a first go --- as you say it's messy.

I'm using SOSE for my boundary conditions including sea ice.  I do have some concerns as to how well SOSE is representing the sea ice, especially at the eastern boundary of my domain.
