Abstract
Estimations of the effects of galactic cosmic rays (GCR) on chemical composition of the troposphere and stratosphere in view of known mechanisms of formation of NO and OH under impact of GCR have been made. It has been shown that GCR may significantly change a chemical composition of the upper troposphere and the stratosphere. However, GCR do not influence on an abundance of H-containing greenhouse gases (such as methane and ozone-harmless freons) but can noticeably reduce the concentration of atmospheric ozone. Those estimations have shown a necessity to take into account the influence of GCR on the composition of the atmosphere at the analysis of ozone related processes and, in particular, at forcasting recovery of the ozone layer.
