Global vegetation gross primary production estimation using satellite-derived light-use efficiency and canopy conductance

Yebra, Marta; Van Dijk, Albert; Leuning, Ray; Guerschman , Juan Pablo

Description

Climate and physiological controls of vegetation gross primary production (GPP) vary in space and time. In many ecosystems, GPP is primary limited by absorbed photosynthetically-active radiation; in others by canopy conductance. These controls further vary in importance over daily to seasonal time scales. We propose a simple but effective conceptual model that estimates GPP as the lesser of a conductance-limited (F<inf>c</inf> ) and radiation-limited (Fr) assimilation rate. F<inf>c</inf> is...[Show more]
