六个世界气象组织(WMO)/全球大气监视（GAW）站位于中国的背景站点，它们构成了一个监测地面臭氧及其长期时间变化的网络。本研究利用2010-2012年WMO/GAW背景站观测资料，对ECHAM/凌乱大气化学（EMAC）环流模式模拟的地表臭氧季节变化进行了评价，并探讨了各背景站地表臭氧季节变化的区域代表性。在EMAC模拟的基础上，我们使用标记示踪方法确定了来自对流层和平流层不同纬度带的臭氧的贡献。结果表明，北半球中高纬度和热带地区对流层对地面臭氧的贡献最大。对于每一个台站来说，其周围有一大片区域的年臭氧最大值发生在该站相同的月份，这反映了WMO/GAW背景台站记录的地表臭氧季节性变化的区域特征。中国地面臭氧总体上在夏季高峰，而在非季风和中纬度季风区高峰，在春季高峰，这表明中国臭氧变率的区域代表性受亚洲夏季风的显著影响。
Six World Meteorological Organization (WMO)/Global Atmosphere Watch (GAW) stations are located at background sites in China, which constitute a network for monitoring surface ozone, including its long-term temporal variation. In this study, we evaluated the seasonal variation in surface ozone simulated by the ECHAM/MESSy Atmospheric Chemistry (EMAC) general circulation model with the measurements made at these WMO/GAW background stations for the period of 2010–2012, and investigated the regional representativeness of each station with respect to the seasonal variation in surface ozone. We determined the contributions of ozone originating from various tropospheric and stratospheric latitude bands based on EMAC simulations using a tagged tracer approach. The results showed that the predominant contribution to surface ozone was from the troposphere in northern middle-high and tropical latitudes. For each station there was a large surrounding area in which the yearly ozone maximum occurred in the same month as it did at the station, reflecting the regional characteristics of the seasonal variation in surface ozone recorded at the WMO/GAW background stations. Surface ozone in China was found to generally peak in summer over non-monsoon and mid-latitude monsoon regions and in spring over low-latitude monsoon regions, indicating that the regional representativeness of ozone variability in China is significantly influenced by the Asian summer monsoon.
