CAREER: Evaluating Secondary Organic Aerosol Formation Processes

这一职业计划的研究部分将调查导致二次有机气溶胶(SOA)形成的过程。该计划将重点研究氮氧化物(NOx)对SOA形成潜力的影响，实验研究气溶胶形成前体混合物形成的SOA，并评估温度和相对湿度对几个离散系统的影响。这项研究将使用一个新的、独特的环境舱来研究低NOx和碳氢化合物浓度下的SOA过程，这是以前不可能实现的。该计划将促进我们对气体-颗粒平衡的理解，并为评估其他当前和未来的SOA预测模型提供一个关键的数据库。这项工作的结果将为预测大气中的气溶胶形成过程提供重要的洞察和进展。这项研究与空气污染控制、公共健康和能源战略等公共政策相关。该项目的教育部分将为K-12学生提供新的教学模块，让他们了解空气污染。这项研究将为空气质量研究和空气质量教育领域的研究生和本科生提供培训。学生将通过与当地教育工作者就该地区的空气质量进行团队教学，直接参与当地学区新K-12模块的开发和实施。该研究计划将通过让该地区未被充分代表的当地学生了解空气质量，并继续培训高度多样化的学生群体，来促进少数民族教育。

The research component of this CAREER program will investigate processes leading to the formation of secondary organic aerosol (SOA). The program will focus on the impact of oxides of nitrogen (NOx) on SOA formation potentials, experimentally investigate SOA formation from mixtures of aerosol forming precursors, and evaluate the impact of temperature and relative humidity for a discrete number of systems. The research will use a new, unique environmental chamber for investigation of SOA processes at low NOx and hydrocarbon concentrations that have not been possible previously. The program will advance our understanding of gas-particle equilibria and provide a critical database for evaluation of other current and future SOA predictive models. The results of this work will provide critical insight into and advances in the prediction of aerosol formation processes within the atmosphere. This research is relevant for public policy on air pollution control, public health, and energy strategy.The educational component of the program will generate new teaching modules for K-12 students to understand air pollution. The research will provide for the training of graduate and undergraduate students both in the area of air quality research and in air quality education. The students will be directly involved in the development and implementation of the new K-12 modules in the local school districts by team teaching with local educators about air quality in the region. The research program will advance minority education by interesting local underrepresented students in the region about air quality and by continuing to train a highly diverse student body.
