地面臭氧的变化规律和计算方法的初步研究——Ⅱ.可见光波段

A Preliminary Study of the Variational Regularity and Calculating Method of Surface Ozone Part II: Visible Band

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等微量气体及太阳可见光辐射的变化规律,详细讨论了可见光波段、不同天气条件地面O3与NOx、光化学反应、气溶胶、可见光辐射等之间复杂的关系。提出以光能量传输与守恒的观点来考虑大气中与可见光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,计算值与观测值吻合得均比较一致。

Based on the observational and theoretic analysis on surface ozone. NOx, actinic radiation and meteorological parameters at Dinghushan biosphere reserve, Zhaoqing city. Guangdong province, the varialional regularity of trace gases, such as O,. NOX. and solar visible radiation are given. The ex haustive study is carried oul on complicated relationship between O, and NOX, photochemical reaction, aerosol, solar visible 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. Ihc calculated value of surface ozone agrees well with observed at different conditions.
