摘要
本文介绍了1987—1989年在以重庆、成都和贵阳三地区为代表的西南地区进行了地面和低层大气臭氧的观测结果,给出了该地区大气臭氧时空分布的一些特征.分析表明,成都、重庆和贵阳等地区O_3浓度的时空分布及变化规律不尽相同,但都与前体污染物特征以及日照强度、大气层结稳定度.天气过程等密切相关.
The ozone (O3) concentrations at the ground surface in the lower troposphere (from the ground to 4.5km above sea level )were measured in Southwest China during 1987- 1989, and some basic characteristics of the temporal spatial distributions on the O3 concentrations in this region are presented in this paper. The results show that the characteristics of temporal and spatial distributions in Chengdu, Chongqing and Guiyang in Southwest China are different, but they are all closely related to the features of precursory pollutants of ozone and to insolation in -tensity, atmospheric stratification stability, weather process, precipitation and so on.
