We present the study of correlation between the intensity of the UV solar radiation and the content of surface ozone in Kola Peninsula for 1999, 2000, and 2001. The diurnal variation has been revealed in the ozone concentration that grows from spring to fall (from 0% in March to 20% in September). Statistically significant correlation has been found between the UV radiation and the surface ozone concentration. No influence of the extraterrestrial short-wave UV radiation on the surface ozone has been found. Numerical simulation of the ozone generation and absorption processes in the surface atmospheric layer has shown that the increased diurnal ozone variation in fall may be the result of a combined action of the UV radiation and high concentration of the ozone precursors (the organic peroxyradicals in that case), whose appearance in the atmosphere is characteristic of the summer-fall period.
