[MITgcm-support] heat flux components

[Patrick Heimbach]

Mike, 

not sure whether anyone replied?

Qnet is indeed total net heat flux, but upward, i.e.
C     Qnet  :: Net upward surface heat flux (including shortwave) in W/m^2
C              Qnet = latent + sensible + net longwave + net shortwave
C              > 0 for decrease in theta (ocean cooling)
C              Typical range: -250 < Qnet < 600
C              Southwest C-grid tracer point
(see model/inc/FFIELDS.h)

Sensible and latent heat fluxes are currently not saved, unfortunately.
They are local variables, living in pkg/exf/exf_bulkformulae.F
sensible: hs(...), latent: hl(...)
It's a good suggestion to diagnose/save them,
and on the to-do list now.
