本文利用第五代中尺度气象模式（MMS）/社区多尺度空气质量模式（CMAQ）集成的嵌套模式，对北京市2001年冬、夏季的空气质量进行了研究。美国国家航空航天局（NASA）的太平洋运输和化学演变（TRACE-P）排放清单用于36公里（东亚）、12公里（华东）和4公里（大北京地区）的区域。此外，我们开发了一个本地的北京排放清单，用于在4公里的域。我们还构建了一个确证的化学物种之间的映射TRACE-P库存和碳键IV（CB-IV）的化学机制之前，集成的模拟系统应用于研究臭氧（0，）和颗粒物（PM）在北京举行。综合模拟运行的气象数据从MM 5中提取。模型结果显示，0，小时浓度范围内。在夏季，城市地区为十亿分之80-159（ppb），在城市的顺风处高达189 ppb。高细颗粒物（PM2.5）浓度（月平均75微克。m（-3），夏季为150 μ g . m（-3）冬季）在大城市和下风向地区进行了模拟，并有显著的次级成分。并与北京市现有的O3和PM测量数据进行了比较。我们建议改进开发的本地北京排放清单，以提高北京的空气质量模拟。4公里的模式配置也被推荐用于制定空气污染控制策略。
This paper examines Beijing air quality in the winter and summer of 2001 using an integrated air quality modeling system (Fifth Generation Mesoscale Meteorological Model [MMS]/Community Multiscale Air Quality [CMAQ]) in nested mode. The National Aeronautics and Space Administration (NASA) Transport and Chemical Evolution over the Pacific (TRACE-P) emission inventory is used in the 36- (East Asia), 12- (East China), and 4-km (greater Beijing area) domains. Furthermore, we develop a local Beijing emission inventory that is used in the 4-km domain. We also construct a corroborated mapping of chemical species between the TRACE-P inventory and the Carbon Bond IV (CB-IV) chemical mechanism before the integrated modeling system is applied to study ozone (0,) and particulate matter (PM) in Beijing. Meteorological data for the integrated modeling runs are extracted from MM5. Model results show 0, hourly concentrations in the range of. 80-159 parts per billion (ppb) during summer in the urban areas and up to 189 ppb downwind of the city. High fine PM (PM2.5) concentrations (monthly average of 75 mu g . m(-3) in summer and 150 mu g . m(-3) in winter) are simulated over the metropolitan and downwind areas with significant secondary constituents. A comparison against available 03 and PM measurement data in Beijing is described. We recommend refinements to the developed local Beijing emission inventory to improve the simulation of Beijing's air quality. The 4-km modeling configuration is also recommended for the development of air pollution control strategies.
