Abstract

Analysis of data from long observations of atmospheric transparency at stations Murmansk, Arkhangelsk, and Leningrad has shown that in a number of solar cosmic ray events with high intensities of solar protons, atmospheric transparency deteriorates. In all cases, this deterioration is associated with the aerosol weakening effect. A two- to fourfold increase in the concentration of large aerosol particles from 0.1 to 1.0 \mum in radius was observed.
