[MITgcm-devel] Seaice wind-stress diagnostics

[Martin Losch]

Hi Jean-Michel,

you are absolutely right SIfu/fv are duplicates and we don’t need them (if fu and fv are diagnosed ***after*** calling seaice_model, which seems to be the case.). Similar: SIempmr, SIqnet, SIqsw (-oceFWfx, -oceQnet)

I don’t think that we have a diagnostics for sea-ice-atmosphere stress. 
The atmosphere sea ice stress is calculated in seaice_get_dynforcing and stored in taux/tauy, which are fields local to pkg/seaice and can be easily included in seaice_model? Or do it in seaice_get_dynforcing?
