南京北郊春季地面臭氧与氮氧化物浓度特征
Concentration characteristics of surface ozone and nitrogen oxides in north suburb of Nanjing in spring
摘要
Abstract
To investigate the variation characteristics of O3 and NOx concentration in spring in northern sub- urban of Nanjing, concentrations of O3 , NO, NO2 and NO in the atmospheric were measured continuously with NO-NO2-NH3analyzer and O3 analyzer from March to May 2009. Results indicated that diurnal variation of O3 concentrations appeared the shape of single peak type, and O3 concentrations of daytime were higher than that of night. Peak O3 concentrations appeared at about 14：00, while the lowest O3 concentrations appeared at about 06：00. And O3 concentrations on weekdays were higher than that on weekends. Diurnal variation of NOx concen- trations were double peak styles. Peaks of NOx concentrations appeared at about 07：00 and 23：00, meanwhile, the lowest concentrations appeared at about 14：00--15：00. From March to May, NO daily average concentra- tions decreased significantly and had bigger variety range in March, at the same time, NO2 daily average concen- trations raised obviously and had bigger variety range in May. There was significant negative correlation between NO and O3 from March to May, and significant negative correlation was found between NO2, NOx and O3 from April to May.关键词
