AbstractThe revealed trends in temperature and pressure based on rocket data analysis (Russian station Volgograd, 48,7 N; 1970–1990) has been used to calculate respective changes in chemical composition including ozone. The magnitudes of trends has been used in 1D photochemical model. Long-term changes in basic atmospheric parameters influence on gas-phase chemistry determining ozone production and change the photolysis rates. The results of such photochemical simulations gave trend in vertical distribution of ozone content. Vertical structure of such calculated trend has layered structure with negative effect (about −1%/Year) in the mesosphere.
