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.

Products derived from ocean colour remote sensing (OCRS) contain information on the ocean albedo and information on the constituents of the seawater, in particular, phytoplankton pigments such as chlorophyll-a.
