G_bi

Calculates the direct beam solar irradiance incident on an inclined surface on Mars.
Accounts for the sun's angle of incidence on the tilted and oriented surface. Based on
Appelbaum, Flood &amp; Norambuena (1994).

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.
