摘要
利用2 0 0 2年7月1 9日至8月2 0日,北京32 5m气象塔臭氧、氮氧化物浓度梯度观测资料及同期的气象资料,研究了臭氧浓度的时空分布及垂直变化规律,并从光化学的角度,分析了近地层气象条件如温度、风速、相对湿度对污染物浓度的影响,探讨了污染物间的相互关系,为今后开展光化学污染的潜势预报提供物理依据和预报思路.
Utilizing the vertical measurement data of O 3 and meteorological factors obtained on the Beijing 325m meteorological tower from July 19 to August 20, 2002, we dealt with the temporal, spatial and vertical distribution of ozone, analyzed the importance of meteorological factors and their impact on relevant pollutant concentration levels from chemical aspects,and discussed the relationship among these pollutants. All these results will provide a physical basis for accurately predicting photochemical pollution in extensive, further research.
