利用2008年1-12月南京北郊O3、NO2及SO2质量浓度连续观测资料,分析了南京北郊气体污染物(O3、NO2、SO2)的质量浓度变化规律。结果表明:南京北郊O3浓度夏季较高,日变化曲线呈单峰型,NO2和SO2浓度夏季较低,日变化曲线呈双峰型,NO2与O3的日变化呈现负相关关系,该地区SO2浓度整体较高,夏季周末效应NO2和SO2较O3更明显。

Based on the atmospheric pollutants data from the differential optical absorption spectroscopy(DOAS) system in Nanjing University of Information Science and Technology,the mass concentrations of O3 ,NO2 and SO2 in the northern suburb of Nanjing from January to December in 2008 were analyzed.The results indicate that the monthly mean mass concentrations of O3 are high in summer,while both mass concentrations of NO2 and SO2 are low in summer.The diurnal variation curve of O3 mass concentrations is mono-modal,while both curves of NO2 and SO2 mass concentrations are bimodal.The correlation between diurnal NO2 and O3 mass concentrations is nega-tive.The SO2 mass concentrations are generally high in this region,and the weekend effect is more apparent for NO2 and SO2 than for O3 in summer.
