[MITgcm-support] Evaporation in sea ice regions

[Naughten, Kaitlin A.]

Hello,


I am trying to calculate evaporation in my domain, which contains both sea ice and open ocean. I can't figure out what the EXFevap diagnostic represents in sea ice covered regions. Is it the evaporation which actually happens (i.e. considering the sea ice) or the evaporation which would have happened if there was no sea ice (based on the SST below the ice)?


Furthermore, is sublimation included in the evaporation fields, or is this completely separate? I see some sublimation diagnostics (SIfwSubl, SIacSubl, SIrsSubl) but am not sure if adding them to evaporation would be double-counting.


Many thanks,

Kaitlin Naughten
