摘要
以葫芦岛市2014—2016年臭氧(O_3)监测数据为基础分析了O_3浓度变化特征。结果表明:葫芦岛市O_3污染有明显的加重趋势;O_3污染天气集中出现在4-10月;O_3浓度的日变化特征呈现单峰分布,峰值出现在15:00,谷值出现在06:00;O_3前体物(NO、NO_2、CO)浓度休息日低于工作日,O_3浓度休息日高于工作日,波动幅度大于工作日,"周末效应"不显著。
The characteristics of ozone concentration changes were analyzed based on the observational data of ozone from 2014 to 2016 in Huludao.The results showed that the pollution of ozone in Huludao had been aggravating significantly and the pollution was basically concentrated during the period from April to October.The daily variation of ozone concentration showed a unimodal distribution with the valley value appeared at 06：00 while the peak value appeared at 15：00.The concentrations of ozone precursors（NO,NO2,CO） observed during weekend were lower than that observed during the working days,while the concentration of the ozone itself was in reversed situation but with a fluctuation greater than working days,demonstrating a less significant ＂ weekend effect＂.
