| 英文摘要 | In recent years, China has made certain progresses regarding the monitoring of ozone (O-3) pollution. However, a comprehensive understanding of the three-dimensional distribution and evolutionary characteristics of O-3 is still relatively lacking. This study analyzed an O-3 pollution episode in the Pearl River Delta during September to October 2019 using data from five O-3 lidars and air pollution monitoring stations combined with the Gridpoint Statistical Interpolation data assimilation system. The model's performance in the vertical direction improved after assimilation, with the correlation coefficient of model simulations improving by 87 %, errors decreasing by 30 %, and simulation accuracy increasing by 29 %. Results showed that O-3 pollution persisted for more than a week due to high temperatures and the influence of Typhoon Mita. However, after October 2, the concentration of O-3 decreased under the combined effects of southerly winds and reduced traffic emissions during the National Day period. Besides, lidar observations indicate that residual O-3 at night can disrupt its typical diurnal variation patterns. Moreover, O-3 pollution occurred both at ground level and greater heights. Overall, O-3 is primarily produced by photochemical reactions. Nevertheless, the O-3 concentration was also affected by pollutant transport from northeast to southwest at a height of 0-3 km during the pollution period, with an average transport flux of 366 mu g |
