It is approximately 80%, which is a realistic maximum for the clear Rayleigh sky during day time. The video thus begins when the sun is slightly above the horizon and at an azimuth of 120°. The sky is highly polarized in the effective North-Zenith-South plane. This is slightly offset because the sun's azimuth is not due East.
Rayleigh scattering of sunlight in Earth's atmosphere causes diffuse sky radiation, which is the reason for the blue color of the daytime and twilight sky, as well as the yellowish to reddish hue of the low Sun. Sunlight is also subject to Raman scattering, which changes the rotational state of the molecules and gives rise to polarization ...
The Horizon universe was adapted into a comic book in 2020, with the release of Horizon Zero Dawn: The Sunhawk. [11] The comic book bridges the gap between Horizon Zero Dawn and Forbidden West. A second comic set during the events of the first game, called Horizon Zero Dawn: Liberation, was released in 2021. [12]
which is the Rayleigh distribution. It is straightforward to generalize to vectors of dimension other than 2. There are also generalizations when the components have unequal variance or correlations (Hoyt distribution), or when the vector Y follows a bivariate Student t-distribution (see also: Hotelling's T-squared distribution).

The above image shows the degree to which Rayleigh scattering scatters blue light more intensely than red light. The scattering curve shown is calculated for sunlight passing vertically through the atmosphere and is based on Bucholtz, Anthony (1995). "Rayleigh-scattering calculations for the terrestrial atmosphere". Applied Optics 34 (15).
The individual absorption spectra of major greenhouse gases plus Rayleigh scattering are shown in the lower panel. [1] An atmospheric window is a region of the electromagnetic spectrum that can pass through the atmosphere of Earth. The optical, infrared and radio windows comprise the three main atmospheric windows. [2]

The color of light from the sky is a result of Rayleigh scattering of sunlight, which results in a perceived blue color. On a sunny day, Rayleigh scattering gives the sky a blue gradient, darkest around the zenith and brightest near the horizon.
