项目摘要

This project is focused on elucidating the chemical and physical processes that control the atmospheric oxidation of biogenic volatile organic compounds (BVOC) in the atmosphere and the subsequent formation of secondary organic aerosol (SOA). It is also investigating the influence of anthropogenic pollution on these processes. The project is part of a collaborative field study located in the Amazon region around Manaus, Brazil. NSF previously funded this principal investigator to evaluate the role of BVOC in forming secondary organic aerosol in southern forests in Alabama, as part of the Southern Atmosphere Study (previously named SOAS) in the summer of 2013. The Amazon site is complimentary to the Alabama site, with critical differences. These differences allow this work to be applicable to diverse ecosystems and socio-economic regions. The Alabama site has high aerosol loading and large regional cooling due to aerosols, and the Amazon site has low aerosol loading in a region that is rapidly developing and undergoing substantial land use change leading to increasing anthropogenic emissions.The project will result in the first chemically speciated in situ measurements in the Amazon of oxidation products from biogenic volatile organic compounds. The effort will contribute to a better understanding of climate change and air quality issues. This project contributes to a larger study, GOAMAZON-2014, funded by the U.S. Department of Energy.

该项目的重点是阐明控制大气中生物挥发性有机化合物（BVOC）的大气氧化和随后形成二次有机气溶胶（SOA）的化学和物理过程。它还在调查人为污染对这些进程的影响。该项目是位于巴西马瑙斯周围亚马逊地区的合作实地研究的一部分。NSF之前资助了这位首席研究员，以评估BVOC在形成亚拉巴马南部森林次生有机气溶胶中的作用，作为2013年夏季南方大气研究（以前称为SOAS）的一部分。亚马逊网站是免费的亚拉巴马网站，有关键的区别。这些差异使这项工作适用于不同的生态系统和社会经济区域。亚拉巴马站点的气溶胶含量高，由于气溶胶，区域冷却大，亚马逊站点的气溶胶含量低，该地区正在迅速发展，并经历了大量的土地使用变化，导致人为排放量增加，该项目将导致在亚马逊的第一个化学物种的氧化产物的生物挥发性有机化合物的现场测量。这项工作将有助于更好地了解气候变化和空气质量问题。该项目有助于由美国能源部资助的更大的研究，GOAMAZON-2014。
