Hi Renske,

You are correct, and there is a simple experiment with cheapaml+seaice+thsice
in Contrib (still under CVS):
 MITgcm_contrib/verification_other/offline_cheapaml
that could help, especially the secondary test in input.dyn/.

Cheers,
Jean-Michel

When I first got started, it was not possible (or at least I was not aware of the possibility as the documentation said it was not possible, though it may have been out of date) to use the SEAICE package dynamics with THSICE thermodynamics, so I use the default zero-layer thermodynamics.

There appear to be a few compatibility issues, however, and, being a newbie in incorporating atmospheres in models, I would like some advice from the experts on these packages before I start hacking. To start at the end: I think it should be possible to use CHEAPAML with SEAICE+THSICE without EXF.
