  2. Diffuse sky radiation - Wikipedia

    en.wikipedia.org/wiki/Diffuse_sky_radiation

    The blue sky spectrum contains light at all visible wavelengths with a broad maximum around 450–485 nm, the wavelengths of the color blue. Diffuse sky radiation is solar radiation reaching the Earth 's surface after having been scattered from the direct solar beam by molecules or particulates in the atmosphere .

  3. Rayleigh sky model - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_sky_model

    The Rayleigh sky model describes the observed polarization pattern of the daytime sky. Within the atmosphere, Rayleigh scattering of light by air molecules, water, dust, and aerosols causes the sky's light to have a defined polarization pattern. The same elastic scattering processes cause the sky to be blue.

    en.wikipedia.org/wiki/Blue_Sky_Solar_Racing

    As Blue Sky Solar Racing's first project, Blue Sky Project served as an experimental effort for the team to learn more about the production of solar vehicles. The vehicle was designed as a single-seated four-wheeler with a weight of 850 lbs. [ 11 ] The project was completed in 1997 and was immediately put to test at the Florida SunDay Challenge ...

  6. Sun path - Wikipedia

    en.wikipedia.org/wiki/Sun_path

    A 2021 publication [8] about solar geometry first calculates the x-, y-, and z-component of the solar vector, which is a unit vector with its tail fixed at the observer's location and its head kept pointing toward the Sun, and then uses the components to calculate the solar zenith angle and solar azimuth angle. The calculated solar vector at 1 ...
