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 NOx, 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 NOxand CO concentration. In the range of 33 to 38'C, the variations of O3 concentration show antisymmetric to that of NOx 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.
