CAREER: Evaluating Secondary Organic Aerosol Formation Processes

该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。该计划将侧重于氮氧化物（NOx）对SOA形成潜力的影响，实验研究SOA形成气溶胶形成前体的混合物，并评估温度和相对湿度对离散系统的影响。该研究将使用一个新的，独特的环境室，在低NOx和碳氢化合物浓度下调查SOA过程，这在以前是不可能的。该计划将推进我们对气体-颗粒平衡的理解，并为评估其他当前和未来的SOA预测模型提供关键数据库。这项工作的结果将提供关键的洞察力和在大气中的气溶胶形成过程的预测进展。该研究与空气污染控制，公共卫生和能源战略的公共政策相关。该计划的教育部分将为K-12学生提供新的教学模块，以了解空气污染。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。学生们将直接参与当地学区新K-12模块的开发和实施，与当地教育工作者一起进行有关该地区空气质量的团队教学。该研究计划将通过对该地区空气质量感兴趣的当地代表性不足的学生以及继续培养高度多样化的学生群体来推进少数民族教育。

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.
