optical_depth

Calculates the optical depth of the Martian atmosphere as a function of latitude and season.
The optical depth varies spatially and temporally, with peaks during global dust storms.
Implements Equations 1 and 2 from Appelbaum, Landis &amp; Sherman (1991).

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.
