[MITgcm-devel] [MITgcm-support] maintaining sea ice coverage over multi-year run on cs32

[Jean-Michel Campin]

Dimitris,

Just regarding this:
> Initially, best to check in ifdefed and off by default until it's been vetted a little bit, no?
I would prefer to have a default that is consistent (meaning, it there is
latent heat flux due to sublimation, there should be sublimation).

Cheers,
Jean-Michel

I had to introduce it because the ice model kept creating water (ice) volume, because the sublimation part is accounted for in the latent heat flux (seaice_budget_ice) but not in the volume part. In this context, I realized again, how poorly written this seaice_growth routine is. It's such a drag to try and change anything in there.

I guess we should have CPP flags around it, have them defined by default and then turned off in verification experiments? Or rather vice versa (you'd have to turn them on yourself, ie. you have to know about this)?
