62    C     are defined in exf_fields.h
63    C
64    C     #ifdef SEAICE_EXTERNAL_FLUXES, additional forcing fields, fu,
65    C     fv, Qnet, Qsw, and EmPmR, as defined in FFIELDS.h, are required.

69    C
70    C     Downward and net radiative fluxes are not the same !!!
71    C     Downward radiative fluxes, swdown and lwdown, are used by
