In ilyamaclean/microctools: Various worker functions for microclimc package

Calculates the fraction of sunlit leaves

Description

psunlit calculates the fraction of sunlit leaves for application of radmult

Usage

psunlit(l, x, sa, clump = 0)

Arguments

l	leaf area index
x	leaf angle distribution coefficient (ratio nof horizontal to vertical projection of foliage)
sa	solar altitude (decimal degrees)
clump	clumpiness factor for canopy (0-1, see details)

Details

if clump = 0 the canopy is assumed entirely uniform and the sunlit proportion is as for a turbid medium. As clump approaches 1, the canopy is assumed to be increasingly patchy, such that a greater proportion of the canopy is sunlit.
