“…(7) with regard to the obtained dependence A 0 (t), we find the coefficient p A entering formula (3). Actually, it is equal to polarization of the atmospheric component of the sky background near the horizon.…”

This paper is devoted to the analysis of the results of wide-angle polarimetric observations of the night sky, which has been carried out in December 2002 in the Southern Laboratory of Shternberg State Astronomical Institute (Crimea, Ukraine) in a color band close to the V band (the effective wavelength is 5250 Å). We propose a method with the help of which the sky light was separated into basic components: the atmospheric glow, emission of weak stars, and the zodiacal light. The polarization map of extra-atmospheric emission of five sky zones close to the ecliptic is constructed, and it is shown that polarization of the sky background far from the antisolar point is determined, in the main, by the zodiacal light. For each observational period, the time dependence of the atmospheric luminosity and absorption is obtained.

“…The measurements were carried out with 80-s interval for three positions of the polaroid axis spaced by 120° from each other. The same polarization filter was used, as in atmospheric measurements of 2000 [3], its polarization degree in the given color band exceeds 99.9%. The time of each exposure was 18 s.…”

“…The results turned out to be in a good agreement with the data of numerical integration [4], and they explained the color and polarization evolution of the twilight sky as the Sun submerged under the horizon. However, as was pointed out in [3], this method is applicable only in the case when the contribution of single aerosol scattering is small. This took place for most observations in violet, blue, and yellow rays.…”

“…However, the contribution of single aerosol scattering turned out to be quite significant in the red part of the spectrum. On the one hand, this makes difficult to use this method in that form in which it was suggested in [2,3]. On the other hand, this opens up new possibilities to study the aerosol scattering.…”

“…At the same time, they use a less stringent system of assumptions. A similar method was developed in [2,3] in order to calculate the contribution of multiple scattering to the general background of the twilight sky based on polarization measurements. The results turned out to be in a good agreement with the data of numerical integration [4], and they explained the color and polarization evolution of the twilight sky as the Sun submerged under the horizon.…”

The paper is devoted to studies and a quantitative estimation of the influence of scattering of direct solar radiation by particles of tropospheric aerosols in the period of light twilight, close to sunrise and sunset. Polarization measurements of the twilight sky in two broad spectral bands lying near the standard bands V and R form the basis of these studies. The measurements were carried out in 2002 and 2003 at the Southern Laboratory (Crimea) of the Sternberg Astronomical Institute. The twilight period during which the single aerosol scattering becomes significant is isolated. The character of its influence on the intensity and polarization of the twilight sky is demonstrated. A method is suggested to evaluate polarization of the single aerosol scattering and its contribution to the general brightness of the twilight sky background. The method is based on differential characteristics of the background near the zenith and on their correlations with each other.
