In recent years, the rapid development of industry and economy, has resulted in increasingly severe and frequent air quality problems. With the deepening of air pollution research, ozone pollution has received more and more attention. Nowadays, the current concentration of ozone in the troposphere has been significantly exceeded, as a significant pollutant, has a major threat to the human living environment, and has aroused the great attention of the international community.
This present paper studies the variation of ozone concentration in Hong Kong and analyzes the causes based on the actual situation. This present paper selects and analyzes data from four sites in Hong Kong. The ozone concentration has a significant diurnal variation, with two peaks, one in the morning and one in the afternoon. The ozone concentration is inversely proportional to the amount of precipitation and the amount of cloud cover, but is proportional to the amount of radiation. Seasonally, Hong Kong has the highest average ozone concentration in autumn and the lowest ozone concentration in summer. The degree of dispersion of summer pollution is the smallest, and the degree of dispersion is the largest in autumn. Suburban ozone concentration in Hong Kong is higher than the city center. Ozone levels in Hong Kong are generally acceptable, but still, need to be improved.
