| 摘 要： | 2000年夏季7～8月,以北京325m气象塔为观测平台,分别在8,120,280m高度上进行了大气污染物臭氧(O3)及其前体物氮氧化物(NOx)和气象要素加强期的同步观测.对观测资料的分析表明,边界层内存在明显的臭氧浓度垂直差异;低层臭氧浓度呈明显的日变化,且昼夜振幅较大;对O3浓度与NO2/NO的比值作线性拟合分析发现,白天(10:00～16:00)O3浓度与NO2/NO]的比值成线性关系,即达到光化学稳定态,但受气象背景场影响较大.

| Abstract: | Based on the Beijing 325 m meteorological tower, O3, NOx atmospheric pollutants and meteorological essential factors in strengthened period were observed synchronously from July to August of year 2000 on 8, 120 and 280 m high levels respectively. Concentrations of O3 in boundary layers exist remarkably different vertically; the concentrations show daily variation clearly in the low level with greater variation between daytime and nighttime, and fitting analysis finds that the relation between O3 concentration and NO2/NO ratio is linear during the daytime of 10:00~16:00 i.e. reaches photochemistry equilibrium, but is greatly affected by meteorological background. |
