In order to understand the characteristics of surface ozone concentration and high O₃ concentration days, regional data from seven air quality monitoring stations which were operated by local governments were analyzed. Regional characteristics of O₃ concentration were analyzed with the data of O₃ concentration and the characteristics of O₃ generation and weather conditions by the selection of the days in which the concentration was higher than 80 ppb. In the case of daily variation, the lowest O₃ concentration was shown in all regions from 7am to 8am and the highest around at 4 pm. The monthly variation of mean O₃ concentration and ?O₃ values revealed a reducing pattern in July and August following the peak in June, and again a gradual increasing trend in September and October. The result shows that the amount of ozone is dependent on photochemical reaction.
The days of O₃ generated more than 80 ppb in the region of Gwangyang-bay were 544 days (1,760 hrs). The frequency of occurrence in the region revealed a strong pattern with the order of Samil-dong, Jinsang, and Gwangmu-dong stations in the Gwangyang region. However, Tein-dong, which is the nearest station to air pollution material generation source, showed the lowest frequency in the study area. Consequently, the meteorological parameters which can easily generate the high concentration of O₃ in the region of Gwangyang-bay are characterized as follows; atmospheric temperature which is higher than 19℃, relative humidity with the range of 60~85%, the less average wind velocity than 5 m/s, cloud cover which is less than 5/10, and the more duration of sunshine than 8 hours.
