Collaborative Research: Sensitivity of Gas and Aqueous Phase Production of Secondary Organic Aerosol to Chemical and Environmental Perturbations

这项研究是名为SOAS(南方氧化剂和气溶胶研究)的广泛社区实验的组成部分，旨在进一步调查美国东南部大气环境中植物排放的氧化(生物挥发性有机化合物；BVOCs)。二次有机气溶胶(SOA)颗粒原位产生于BVOCs的大气反应以及这些产物随后被分配到凝聚相材料中。在SOAS研究现场，直接测量SOA产生率和性质对环境条件中各种环境相关扰动的敏感性，将为描述SOA形成的化学机制提供一个方便的试验点，用于各种气候和空气质量模型。该项目将涉及本科生和研究生、研究人员和教职员工，为学生发展和接触跨学科研究与合作创造一个环境。

This research is a component of a broad community experiment named SOAS (Southern Oxidant and Aerosol Study) designed to further investigate the oxidation of the emissions (biogenic volatile organic compounds; BVOCs) of plants in the context of the atmospheric environment of the Southeast United States. Secondary organic aerosol (SOA) particles arise, in situ, from atmospheric reactions of BVOCs together with the subsequent partitioning of these products into condensed phase materials. The direct measurement of sensitivities of SOA production rates and properties to various environmentally relevant perturbations in the ambient conditions at the SOAS study site will provide a convenient test point for the description of the chemical mechanisms of SOA formation, needed for use in a variety of climate and air quality models. The project will involve undergraduate and graduate students, research staff and faculty, creating an environment for student development and exposure to interdisciplinary research and collaboration.
