G_obh

Calculates the solar beam irradiance on a horizontal surface at the top of the Martian
atmosphere (before atmospheric attenuation). Implements Equation 5 from Appelbaum &amp; Flood (1990).

A set of functions to calculate solar irradiance and insolation on Mars horizontal and inclined surfaces. Based on NASA Technical Memoranda 102299, 103623, 105216, 106321, and 106700, i.e. the canonical Mars solar radiation papers.
