The Height of the Twilight Ray,on of the sinking of the sun. This was first demonstrated by V. G. Fesenkov [1] and later examined in detail by N. M. Shtaude [2]. The thickness of the layer that determines the main flow of scattered radiation is not great, so in the first approximation the layer is often replaced by a single ray (

https://doi.org/10.1007/978-3-8348-2340-3The brightness of the sky on the solar almucantar is chiefly determined by the following parameters [1, 2]: the solar zenith distance z., the optical thickness of the atmosphere .. and the albedo of the underlying surface q, and it is greatly dependent upon the form of the scattering indicatrix.

Konstruktion analytischer Funktionen,Twilight phenomena are very complex, since the brightness observed at any point in the sky is the sum of the brightnesses of the primary twilight segment and of higher-order scattering, to which, when the sun has sunk sufficiently below the horizon, we must add the background of the night sky — primarily zodiacal light.
