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年夏季进行的南方氧化剂和气溶胶研究（SOAS）期间部署新型质谱仪器，用于测量中间挥发性有机化合物（IVOC）和半挥发性有机化合物（SVOC）。IVOC和SVOC可能是二次有机气溶胶形成和演变中的重要物质--SOAS的主要研究焦点--但限制很差，并且没有通过常用技术进行真实的实时常规测量。将该仪器部署到SOAS地面现场将填补有机物种清单测量方面的空白，并有助于总体碳核算。 这些测量可能有助于满足SOAS的几个科学目标，包括了解生物源碳的通量和氧化，以及人为排放对生物源气溶胶的影响。该奖项将支持研究生的测量，他们将获得与来自许多不同机构的研究人员合作进行大气化学实地考察的宝贵经验，包括政府和工业科学家。
