![]() We then turn our attention to predicting PAR irradiance on individual leaves, FL, from radiative-transfer models that typically estimate radiant flux densities (or angularly resolved radiances) at given spatial locations or only as lateral averages over sunflecks and shaded areas. ![]() For the moment, we may ignore the phenomena of temperature dependence of photosynthesis (in which total radiative energy balance plays a key role) and of transient responses in photosynthesis. In order to estimate canopy photosynthesis, P can, one must predict PAR irradiances on all the inclined leaf surfaces and one must have a model for responses of individual leaves to irradiance. ![]() The photosynthetic rate of a leaf or a canopy is determined largely by radiation, particularly photosynthetically active radiation, PAR, comprising the 400 to 700 nm band.
