definition	The abbreviation "toa" means top of atmosphere. 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 zenith_angle. A coordinate variable for radiation wavelength should be given the standard name radiation_wavelength. The specification of a physical process by the phrase "due_to_" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. Some of the solar energy absorbed by pigment systems of plant leaves during photosynthesis is re-emitted as fluorescence. This is called solar-induced chlorophyll fluorescence (SIF). It is a radiance that can be measured on a global scale at various wavelengths and by multiple space borne instruments. SIF is considered a measurement of the photosynthetic machinery in plants and can provide a direct approach for the diagnosis of the actual functional status of vegetation. It is therefore considered a functional proxy of terrestrial gross primary productivity which has the standard name gross_primary_productivity_of_biomass_expressed_as_carbon. SIF spans the wavelength range 600 - 800 nm. (en)
