radmult R Documentation
Calculates a multiplication factor for radiation absorbtion by sunlit leaves
Description
radmult calaculates a leaf angle-dependent multiplication factor for sunlit
leaves.
Usage
radmult(x, sa)
Arguments
x
leaf angle distribution coefficient (ratio nof horizontal to vertical projection of foliage)
sa
solar altitude (decimal degrees)
Details
An inclined leaf facing in the direction of the sun will tend to intercept more direct
beam radiation than a horizontal surface. This function uses an approximation of the
x-dependent leaf-angle density function as detailed in Campbell (1990) Agricultural and Forest Meteorology, 49: 173-176
to calculate multiplication factor representing ratio of radiation intercepted by leaves relative
to a horizontal surface.
Value
multiplication factor representing ratio of radiation intercepted by leaves relative
to a horizontal surface
