Diurnal Anisotropic Heat


Description

This tool calculates a rather simple approximation of the anisotropic diurnal heat (Ha) distribution using the formula: Ha = cos(amax - a) * arctan(b) where amax defines the aspect with the maximum total heat surplus, a is the slope aspect and b is the slope angle. For more details see Boehner & Antonic (2009).
