SMARTS2 Version 2.9 - Approximately 20 simple input parameters read by SMARTS2 (Simple Model of the Atmospheric Radiative Transfer of Sunshine) code to produce a terrestrial solar spectral distribution (power as a function of wavelength) transmitted through the atmosphere in the prescribed "state." 32 different optical parameters (transmission functions, optical depths, absorption/scattering properties) are also computed and can be examined as text and in spreadsheets.



Output is important for any application with spectral sensitivity to solar radiation (weathering/durability, day lighting, alternative energy, fenestration, etc.)
