General Comment: Surface heat flux is the rate of exchange of heat, per unit area, crossing the sea surface from ocean to atmosphere. The net heat flux is the sum of turbulent (latent and sensible) fluxes and the radiative (short wave and long wave) components. GCOS IP discerns between those components. Confidence: reasonable
Def: :Not firm, but based on a strong heritage of experiments with similar data
