Abstract

The variation of O₃ concentration was analyzed, and relationship between O₃ and _x, CO concentration was studied in Beijing urban atmosphere. It indicated that no simply rule was found between variation of O₃ concentration and variations of NO_x, CO concentration. O₃ concentration exponentially increased against temperature. In the range of 25 to 38'C,the variation of O₃ concentration was the reverse of that of NO_xand CO concentration. In the range of 33 to 38'C, the variations of O₃ concentration show antisymmetric to that of NO_x concentration. Depended on monthly variation of O₃ concentration,variation of O₃ concentration didn't obey previous theories. It was the most possible reason that liquid water had impact on O₃ concentration.
