Abstract
The direction angle of twilight sky background polarization in the celestial sphere points far from solar vertical is found to depend on the ratio of single and multiple scattering contributions. The polarization direction behavior during the twilight is related with general properties of background components and can be used to check the accuracy of their separation method. The basic assumptions of this method are confirmed by analysis made in this paper. This helps to hold the temperature and scattering medium study in the upper mesosphere, the least accessible layer of the Earth's atmosphere. The mesosphere temperature data obtained during the observations from 2011 till 2014 are also presented.
