项目摘要
This project will develop a better understanding of the formation and transformation of Secondary Organic Aerosol (SOA) and will examine how Biogenic Volatile Organic Compounds (BVOC) interact with anthropogenic pollution to alter the atmosphere's oxidative capacity and enhance SOA formation. Hourly measurements will be made, using a Semi-Volatile Thermal desorption Aerosol Gas chromatograph (SVTAG) system, of speciated vapor and particle phase intermediate and semi-volatile organic compounds during the Southern Oxidant and Aerosol Study (SOAS) to be conducted in Alabama in the summer of 2013. The time-evolution of secondary organic compounds and their precursors will be studied a smog chamber and compared with data from the SOAS campaign to ascertain whether mechanisms observed in the smog chamber are supported by the field data. This study will make a significant contribution to understanding the formation of secondary organic aerosol in a heavily forested region with natural emissions of volatile organic compounds. Emissions of air pollutants from urban areas may enhance secondary aerosol formation. The data collected in this project will be critical to advancing the knowledge and prediction of regional atmospheric chemistry, ozone and secondary aerosol production, and their role in climate processes.
该项目将更好地了解二次有机气溶胶(SOA)的形成和转化,并将研究生物源性挥发性有机化合物(BVOC)如何与人为污染相互作用,从而改变大气的氧化能力并增强SOA的形成。在2013年夏季在阿拉巴马州进行的南方氧化剂和气溶胶研究(SOAS)期间,将使用半挥发性热解吸气溶胶气相色谱仪(SVTAG)系统对特定蒸汽和颗粒相中间和半挥发性有机化合物进行每小时测量。二级有机化合物及其前体的时间演化将在烟雾室中进行研究,并与SOAS活动的数据进行比较,以确定在烟雾室中观察到的机制是否得到现场数据的支持。这项研究将对了解在森林茂密地区挥发性有机化合物自然排放的二次有机气溶胶的形成作出重大贡献。城市地区排放的空气污染物可促进二次气溶胶的形成。该项目收集的数据对于提高对区域大气化学、臭氧和二次气溶胶产生及其在气候过程中的作用的认识和预测至关重要。
