Abstract

In this work on data of measurements of ozone near Tomsk communication of snow cover and change of ground concentration of ozone during 1990-2017 is investigated. It is revealed that it is possible to allocate 4 types of the seasonal course of ozone. Concentration growth which comes to an end with a spring maximum concerns the first. He is observed in 53,9% of cases. The second is characteristic the slow growth and surge in concentration after a snow descent (19,2%). The third differs in the neutral course at snow and sharp surge in concentration after his descent (15,4%). The neutral course without spring maximum (11,5%) is carried to the fourth type. Thus, at the end of the snow period the spring maximum of concentration is observed in 88,5% of cases. Differences in the seasonal courses in different years is explained by temperature dependence of photochemical generation of ozone in the atmosphere.
