Paper Abstract

Ozone is one of the main air pollutants. Now it is suggested that a positive trend of tropospheric ozone concentrations takes place. The question concerning the quality of ozone data, from which O3 trend is evaluated, is very important because on base of this trend are accepted the political and economical decisions directed at ozone pollution reduction. Two methods (ultra-violet optical absorption and chemiluminescence) for surface ozone measurements have been analyzed with respect to the quality of O3 data. The review shows that the ultra-violet (UV) optical absorption method may be influenced by positive interferences from other atmospheric components. It appears that the chemiluminescence method is more interference free.
