This project involves the deployment of novel mass spectrometric instrumentation for measuring intermediate-volatility organic compounds (IVOCs) and semivolatile organic compounds (SVOCs) during the Southern Oxidant and Aerosol Study (SOAS) scheduled for the summer of 2013. IVOCs and SVOCs may be important species in the formation and evolution of secondary organic aerosol--a major research focus of SOAS--but are poorly constrained, and not routinely measured in real time by commonly available techniques. Deployment of the instrument to the SOAS ground field site will close a gap in the measurement of the inventory of organic species, and aid in overall carbon accounting. These measurements may be helpful for meeting several of the SOAS science objectives, including understanding the fluxes and oxidation of biogenic carbon, and the influences of anthropogenic emissions on biogenic aerosol.This award will support measurements made by a graduate student, who will gain valuable experience in carrying out atmospheric chemistry fieldwork, working with researchers from a number of different institutions, including government and industry scientists.

该项目涉及在定于 2013 年夏季举行的南方氧化剂和气溶胶研究 (SOAS) 期间部署新型质谱仪器，用于测量中挥发性有机化合物 (IVOC) 和半挥发性有机化合物 (SVOC)。IVOC 和 SVOC 可能很重要二次有机气溶胶的形成和演化过程中的物种——SOAS 的一个主要研究重点——但受到的限制很少，而且通常无法通过常用的方法进行实时实时测量。技术。将该仪器部署到 SOAS 地面现场将弥补有机物种库存测量方面的差距，并有助于总体碳核算。 这些测量可能有助于实现 SOAS 的几个科学目标，包括了解生物碳的通量和氧化，以及人为排放对生物气溶胶的影响。该奖项将支持研究生进行的测量，他们将获得宝贵的经验在进行大气化学实地考察时，与许多不同机构的研究人员（包括政府和行业科学家）合作。
