摘　　要：利用广州市黄埔区大沙地国控站点观测数据,对2021年4月10~11日的一次臭氧污染过程进行了分析.结果显示,10日和11日大沙地站点臭氧日最大8小时平均值(MDA8)分别为162μg·m^(-3)和187μg·m^(-3),是一次典型的臭氧污染过程.通过对臭氧激光雷达数据分析发现,臭氧污染色带主要集中在1.2 km以下,判断臭氧以本地生成为主;结合气象要素分析,发现高温和低湿环境有利于近地面臭氧的生成.此外,光辐射强度与臭氧污染程度呈明显的正相关.通过对臭氧生成潜势(OFP)数据分析可知,本次臭氧污染受机动车和工业排放VOCs的影响显著.An ozone pollution process from April 10 to 11,2021 was analyzed based on the observation data of Dashadi national control station in Huangpu district,Guangzhou.The result shows a typical ozone pollution process with the maximum daily 8 h average(MDA8)O3concentrations on April 10 and 11 at 162μg·m^(-3)and 187μg·m^(-3)respectively.Ozone lidar data indicates that O3pollution bands were mainly concentrated below 1.2 km,indicating that the O3was mainly generated locally.Combined with the analysis of meteorological elements,it is found that high temperature and low relative humidity are favorable to the generation of surface O3.In addition,the light radiation intensity is positively correlated with the degree of O3 pollution.According to the ozone formation potential(OFP)data,O3 pollution in this study was significantly affected by VOCs emitted by motor vehicles and industry processes.
