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

二次有机气溶胶（SOA）是由大气中碳氢化合物的光化学和氧化过程产生的细颗粒物组分。能够预测SOA的形成是迈向更精确的空气棚和空气质量模型、预测小气溶胶颗粒对健康的影响及其对气候模型的辐射影响的必要一步。这项工作将继续发展半明确的动力学模型，以预测在特定大气条件下生物和人为碳氢化合物、环境氧化剂和现有气溶胶的复杂混合物中SOA的形成，如在北卡罗来纳大学（教堂山）的烟雾室设施中研究的那样。

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).
