Increase of stratospheric aerosols after a solar proton event

摘要

The lidar measurements at Verhnetulomski Observatory ($phi $EQ 68.6$DGR@N, $lambda $EQ 31.8$DGR@E) in the Murmansk region detected the considerable increase of stratospheric aerosol concentration after a solar proton event of GLE (ground level event) type at 16.02.1984. This increase at 17 km altitude reached 40% at 20.02.1984. Some details of trigger influence of high energetic incident solar protons on stratospheric ozone layer, including aerosol formations, are discussed.
