H_dh

Calculates the diffuse solar energy (scattered by atmospheric dust) received over a full
Martian day on a horizontal surface. Obtained by integrating diffuse irradiance from sunrise to sunset.

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.
