Vertical Distributions of Gaseous and Aerosol Admixtures in Air over the Russian Arctic

Data on the vertical distribution of gaseous and aerosol composition of air, measured onboard the Tu-134 Optic airborne laboratory in October 2014 over the Kara Sea and coastal areas of the Russian Arctic, are presented. We revealed the specific features of the altitude distributions of CO2 and aerosol over the Kara Sea as compared to continental conditions. No significant deviations from continental distributions are found for CH4, CO, and O3.
