[Mitgcm-support] Re: sea-ice code

Dimitris,

just as a clarification for me:
This means that by the time you do the CALL SEAICE_MODEL,
dependening on the option, you may have read the data
via exf and converted them either via the exf bulk formulae or the
sea_ice bulk formulae (or both of open ocean/ice) into fluxes, i.e.
the CALL SEAICE_MODEL and CALL EXF_GETFORCING are not exclusive.
Is that right?

That would sound good to me.

-p.
