Global reasonable 2023-09-29 GCOS-245: The 2022 ECVs Requirements (GCOS-245) 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.

Global reasonable 2024-02-09 GCOS-245: The 2022 ECVs Requirements (GCOS-245) Definition in GCOS-245: Ocean colour is the radiance emanating from the ocean normalized by the irradiance illuminating the ocean. 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.
