Description
Compute the fraction of sunlit folige given solar position, LAI and G value with the assumption of the symmetric distribution of leaf azimuth angle.
Usage
1
computeSunlit(Theta, G, LAI)
Arguments
Theta
Solar zenith angle.
G
The G value, namely the projection of foliage area.
LAI
Leaf area index.
Value
The fraction of sunlit foliage.
