When incident radiation intensity approaches zero, the RUE is the initial RUE. How RUE changes with incident radiation intensity depends on the shape of the photosynthetic response curve, which is characterized by the closeness to linear response (CLR) coefficient. If the response curve is linear, CLR is infinite. If the response curve levels off quickly as the incident radiation intensity increases, CLR is small. Initial RUE and CLR differ between diffuse and direct beam radiation. Detailed explanations can be found in (34) and in (36).
