地面臭氧的变化规律和计算方法的初步研究Ⅰ.紫外波段

通过对广州鼎湖山近地面O3、NOx、太阳辐射、气象参数等项目的观测和理论分析,研究了地面O3与NOx等微量气体及太阳辐射的变化规律,详细讨论了紫外波段、不同天气条件地面O3与NOx,光化学反应、气溶胶、光化辐射等之间复杂的关系.用光能量传输与守恒的观点来考虑大气中与紫外辐射有关的主要过程,并以此来研究大气光化学过程中所遵循的能量规律,建立了一个简单、实用、省时的统计模式,用于计算地面O3浓度.结果表明,不同情况下计算值与观测值均吻合较好.

A Primary Study on the Variational Regularity and Calculating Method of Surface Ozone Part I: UV Band

Based on the observational and theoretic analysis on surface ozone, NON, actinic radiation and meteorological parameters at Dinghushan biosphere reserve, Zhaoqing City, Guangdong Province, the variational regularity of trace gases, such as O3, NOx. and solar radiation are given. The exhaustive study is carried out on complicated relationship between O3 and NOx. photochemical reaction, aerosol, actinic radiation. The point of view of transmission and conversation of actinic energy is put forward and applied in the main photochemical processes of surface ozone related to actinic radiation. A simple and practical statistical model is established and applied to calculated surface ozone, the calculated value of surface ozone agrees well with observed at different conditions.
