Paper Abstract

We studied a climatology of ozone concentrations at separate altitude levels over Tomsk and Sodankylä, calculated for 2005-2015 except the anomalous 2011 according to Aura MLS data. The seasonal ozone maximum at heights about 12 km is observed in April over Sodankylä and in May over Tomsk. It is explained by a significant photochemical ozone production due to anthropogenic sources of NOx, CO, and hydrocarbons. The dynamically driven maximum appears at approximately 24-km height in mid-March in Sodankylä and in late March in Tomsk. Later, starting from May-June, photochemical factors dominate at heights of about 30 km and higher. The contribution of circulation overweighs in the autumn, first in October at heights of 20-25 km, and then in November-December at heights of 25-35 km.
