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.
