The study on the relation of surface ozone,NO_x and solar visible radiation in Dinghushan station

摘要：给出了1996年夏季在广东肇庆鼎湖山自然保护区对太阳可见光波段辐射、地面臭氧、NO、NO₂浓度的观测结果,对影响地面臭氧、NO、NO₂的主要因子进行了分析,并得到了较好的结果.晴天条件下,地面臭氧浓度、NO、NO₂浓度有明显的日变化;阴天条件下,地面臭氧浓度、NO、NO₂浓度的日变化要复杂一些.晴天和阴天条件下,在可见光波段辐射因子ln(Q_Vis/m)(Q_Vis为可见光波段辐射,m为大气质量)与地面臭氧、NO、NO₂浓度、整层大气水汽含量(q₁、q₂、q₃、q₄)之间存在着很好的相关关系,其关系式为ln(Qvis/m)=a₁q₁+a₂q₂+a₃q₃+a₄q₄+a₀.同时表明晴天和阴天条件下,大气中的光化学反应是决定地面臭氧、NO、NO₂浓度变化规律的主要原因.

Abstract：The observational results of surface ozone,NO and NO₂ concentrations and solar visible radiation during the summer of 1996 in Dinghushan biosphere reserve, Zhaoqing city,Guangdong province are given.A good result was got from the analysis of key factors affecting the surface ozone,NO and NO₂ concentrations. In clear sky condition,the concentrations of surface ozone,NO and NO₂ show a clear diurnal variation, and in cloudy sky condition, the diurnal variation is complicated. Both in clear sky and in cloudy sky conditions, there is a good correlation between solar visible radiation factor and the concentration of the surface ozone, NO,NO₂ and the water vapor content in whole atmospheric column (q₁,q₂,q₃,q₄); the formula is: ln Q_vis/ m=a₁q₁+a₂q₂+a₃q₃+a₄q₄+a₀. It is proved that the photochemical reaction in the atmosphere is the main cause to control the concentrations of surface ozone, NO and NO₂ in clear and cloudy days.
