surface_ratio_of_upwelling_radiance_emerging_from_sea_water_to_downwelling_radiative_flux_in_air
The surface called "surface" means the lower boundary of the atmosphere. "ratio_of_X_to_Y" means X/Y. Upwelling radiation is radiation from below. It does not mean "net upward". Downwelling radiation is radiation from above. It does not mean "net downward". Radiance is the radiative flux in a particular direction, per unit of solid angle. The direction towards which it is going must be specified, for instance with a coordinate of angle_of_emergence. Radiative flux is the sum of shortwave and longwave radiative fluxes. When thought of as being incident on a surface, a radiative flux is sometimes called "irradiance". In relation to satellite ocean color products the quantity named surface_ratio_of_upwelling_radiance_emerging_from_sea_water_to_downwelling_radiative_flux_in_air is sometimes called "remote sensing reflectance" and has a bidirectional dependence. The direction of the downwelling flux can be specified using a coordinate with the standard name angle_of_incidence.There are no aliases for this term
