The analysis for the variation characteristics of surface ozone and NO_x 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紫外B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,UVB因子与q₁、q₂、q₃、q₄之间存在着很好的相关关系,其关系式为ln(Q_UVB/m)=a₁q₁+a₂q₂+a₃q₃+a₄q₄+a₀.说明大气中的光化学反应是决定地面臭氧浓度、NO、NO₂浓度变化规律的主要原因。

Abstract：The observational results of surface ozone,NO,NO₂ concentrations and solar UVB 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,NO₂ concentrations.In clear sky condition,their diurnal variations was complicated.Both in clear sky and in cloudy sky conditions,there was a good correlation between solar UVB factor and factors of q₁,q₂,q₃ and q₄ which related to the concentration of surface ozone,NO,NO₂ and water vapor contents,the formula is:ln(Q_UVB/m)=a₁q₁+a₂q₂+a₃q₃+a₄q₄+a₀. It was proved that photochemical reaction in atmosphere is the main cause to control the concentrations of surface O₃,NO,NO₂.
