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.

这项研究是一个名为SOAS（南方氧化剂和气溶胶研究）的广泛的社区实验的组成部分，旨在进一步研究美国东南部大气环境中植物排放物（生物挥发性有机化合物; BVOCs）的氧化。 二次有机气溶胶（SOA）粒子的产生，在原位，从大气中的BVOCs反应，连同随后的分配这些产品到凝聚相材料。在SOAS研究现场的环境条件下，SOA生产率和性能的各种环境相关的扰动的敏感性的直接测量将提供一个方便的测试点的SOA形成的化学机制的描述，需要在各种气候和空气质量模型中使用。 该项目将涉及本科生和研究生，研究人员和教师，为学生发展和接触跨学科研究和合作创造环境。
