A Kinetic Model for Predicting Secondary Organic Aerosol Formation in Complex Hydrocarbon Mixtures

二次有机气溶胶（SOA）是由大气碳氢化合物的光化学和氧化过程产生的细颗粒物部分。 能够预测SOA的形成是迈向更准确的空气脱落和空气质量模型，预测小气溶胶颗粒的健康后果及其在气候模型中的辐射影响所需的一步。 这项工作将继续发展一个半明确的动力学模型，以预测SOA的形成在复杂的混合物的生物和人为的碳氢化合物，环境氧化剂和现有的气溶胶在特定的大气条件下，研究在烟雾室设施在北卡罗来纳州（查佩尔山）。

Secondary organic aerosols (SOA) constitute the fine particulate matter fraction arising from the photochemical and oxidative processing of atmospheric hydrocarbons. Being able to predict SOA formation is a needed step forward to more accurate air-shed and air quality models, to predicting the health consequences of small aerosol particles and also their radiative impacts in climate models. This work will continue development of a semi-explicit kinetic model to predict SOA formation in complex mixtures of biogenic and anthropogenic hydrocarbons, ambient oxidants and also existing aerosols under specified atmospheric conditions, as studied in a smog chamber facility at University of North Carolina (Chapel Hill).
