Canopy Physiological Properties

LAI usually acts as the bridge from the leaf model to the canopy model. An important application of LAI is to calculate the canopy stomatal resistance or conductance, which is crucial for determining canopy-level transpiration. Surface resistance describes the resistance of vapor flow through the transpiring vegetation and evaporating soil surface. Analytical integration of leaf resistance yields an estimate of the canopy stomatal resistance:

Where L is the active (sunlit) LAI, rl and rc are the leaf and canopy stomatal resistance, respectively.

In a similar fashion, the rainfall intercepted (pp) by canopy is calculated by

where a is the precipitation interception coefficient of the leaf and pp is the precipitation. The amount of water intercepted will eventually affect the evaporation from the canopy surface.
