In this project, the size-resolved composition of non-refractory submicron aerosol particles will be characterized with an Aerodyne High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS) during the Campaigns of Air Quality Research in Beijing (CAREBEIJING) from July to September, 2008. CAREBEIJING is an international project designed to study the impact of vehicle restrictions and urban emission controls on air quality in Beijing during the 2008 Olympic Games. The resulting data set of time- and size-resolved ambient fine particle composition and high-resolution mass spectra should be valuable for understanding the sources, characteristics, and photochemical processes of atmospheric aerosols in the high-density urban and industrial area. Because vehicle traffic will be restricted during the Olympics, there will be a unique opportunity to examine the impacts of air pollution control on fine particle chemistry, physics, and secondary formation mechanisms in a large megacity.Broader impacts include insights into air quality for residents of Beijing and surrounding regions. Findings from this study will inform the development of air quality management strategies to reduce the adverse impacts of aerosols on human health, ecosystems, and climate. Training in operation of instrumentation and data analysis for collaborators in China will prepare them for future studies of atmospheric chemistry and air quality.

在该项目中，在 2008 年 7 月至 9 月北京空气质量研究活动 (CAREBEIJING) 期间，将使用 Aerodyne 高分辨率飞行时间气溶胶质谱仪 (HR-ToF-AMS) 对非难熔亚微米气溶胶颗粒的尺寸分辨成分进行表征。CAREBEIJING 是一个国际项目，旨在研究车辆限制和城市排放控制对北京空气质量的影响 2008年奥运会期间。 由此产生的时间和尺寸分辨的环境细颗粒成分和高分辨率质谱数据集对于了解高密度城市和工业区大气气溶胶的来源、特征和光化学过程应该很有价值。 由于奥运会期间车辆交通将受到限制，因此将有一个独特的机会来研究空气污染控制对大城市细颗粒化学、物理和二次形成机制的影响。更广泛的影响包括深入了解北京及周边地区居民的空气质量。 这项研究的结果将为空气质量管理策略的制定提供信息，以减少气溶胶对人类健康、生态系统和气候的不利影响。 对中国合作者进行仪器操作和数据分析培训将为他们未来的大气化学和空气质量研究做好准备。
