On a Probability Distribution Convolution Approach to Clear-Sky Index and a Generalized Ångström Equation
(English)Manuscript (preprint) (Other academic)
We show that by modeling solar beam irradiance approximately as a simple Bernoulli distribution and diffuse irradiance as a Gamma distribution, a generalized Ångström equation relating solar irradiation to sunshine hours follows directly as aconsequence of the convolution of beam and diffuseirradiance distributions into a distribution for the clear-sky index.
