Abstract

The paper describes the study of field of scattered radiation in the mesosphere basing on wide-angle polarization camera (WAPC) measurements of the twilight sky background. Mid-August observations in 2012 and 2013 show the decrease of single scattering polarization value that can be related with Perseids meteor dust moderation in the upper mesosphere. Effect correlates with activity of tiny fraction of Perseids shower. Polarization and temperature analysis allows estimating the altitude of dust layer and character polarization of dust scattering.
