Abstract:
... In models of photosynthetic gas exchange, leaf temperature (Tₗₑₐf) is often calculated using a combination of derivations of the energy balance equation and measurements of air temperature (Tₐᵢᵣ). Yet, there are frequently large differences between Tₗₑₐf and Tₐᵢᵣ under natural field conditions, and an energy balance is complicated in complex canopies, especially in tropical ecosystems. In the pres ...
