华北是中国污染最严重的地区之一。北京、天津、唐山等城市和工业中心有许多大型、复杂和强排放源，来自这些污染中心的气团的化学特征预计会有很大的不同。作为“污染对华北地区气溶胶和云微物理的影响"项目的一部分，于2006年4月2日至5月16日在位于京津唐地区中部的新安农村站（39.73°N，117.51°E）进行了地面臭氧和相关痕量气体的测量。本文利用实测资料和区域化学输送模式，研究了华北地区不同污染热点的化学特征及其对臭氧和氮氧化物区域分布的影响。模拟的活性氮化合物归因于不同的排放源在华北地区使用的示踪剂标记方法实现的模式。我们发现，来自不同城市和工业中心的污染羽的化学特征是相当不同的。北京、天津、唐山和石家庄的一般污染羽流的OPEx（定义为氮氧化物（NOx）的臭氧生成效率）估计分别为3.35、2.75、1.43和2.33 mol mol−1。在IPAC-NC外场试验期间，新安站交替地受到来自京津大城市和唐山工业区的气团的影响。北京、天津和唐山到达新安的空气质量的估计值与它们的一般污染羽流的估计值相当。这表明华北不同城市和工业中心的气团在向农村输送的过程中也保持着不同的化学特征。
North China, or Huabei in Chinese, is one of the most severely polluted regions in China. There are many large, complex and strong emission sources in Beijing, Tianjin and Tangshan (together called Jing-Jin-Tang in Chinese) and other urban and industrial centers in Huabei, and the chemical characteristics of air masses coming from these pollution centers are expected to be quite different. As part of the project “Influence of Pollution on Aerosols and Cloud Microphysics in North China (IPAC-NC)”, surface ozone and related trace gases were measured at the Xin'an rural station (39.73°N, 117.51°E), located in the central part of larger Jing-Jin-Tang area, during 2 April-16 May 2006. Here we investigate the chemical characteristics and impact of air masses from these different pollution hotspots on the regional distributions of ozone and nitrogen oxides in Huabei, based on measurement data as well as a regional chemical transport model. Simulated reactive nitrogen compounds are attributed to the different emission sources in the Huabei region using the tracer-tagging method implemented in the model. We find that the chemical characteristics of pollution plumes from different urban and industrial centers are rather different. The OPEx, defined as ozone production efficiency of nitrogen oxides (NOx), for general pollution plumes from Beijing, Tianjin, Tangshan and Shijiazhuang are estimated to be 3.35, 2.75, 1.43 and 2.33 mol mol−1, respectively. During the IPAC-NC field campaign period, the Xin'an site was influenced alternatively by air masses from Beijing and Tianjin megacities and the Tangshan industrial area. The estimated OPExin Beijing, Tianjin and Tangshan air masses arriving at Xin'an are comparable to those in their general pollution plumes. This indicates that air masses from different urban and industrial centers in Huabei also maintain their different chemical characteristics while being transported to the rural areas.
