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).
