c NOTES:
c ======
c
c Input and output units and sign conventions can be customized
c using variables exf_inscal_* and exf_outscal_*, which are set
c by exf_readparms.F
c
c Output fields fu, fv, Qnet, Qsw, and EmPmR are
c defined in FFIELDS.h
c
c #ifndef SHORTWAVE_HEATING, hflux includes shortwave,
c that is, hflux = latent + sensible + lwflux +swflux
c
c If (EXFwindOnBgrid .EQ. .TRUE.), uwind and vwind are
c defined on northeast B-grid U and V points, respectively.
c
c Arrays *0 and *1 below are used for temporal interpolation.
