RAPID: Measurement of Low-Volatility Gas-Phase Organic Compounds during the Southern Oxidant and Aerosol Study (SOAS)

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期间部署新的质谱仪，用于测量中挥发性有机化合物(IVOCs)和半挥发性有机化合物(SVOCs)。IVOCs和SVOCs可能是次生有机气溶胶形成和演化的重要物种--SOAS的一个主要研究重点--但限制很少，而且不能用常用的技术进行常规实时测量。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差距，并有助于全面的碳核算。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。该奖项将支持一名研究生所做的测量，他将在开展大气化学野外工作方面获得宝贵经验，与来自多个不同机构的研究人员合作，包括政府和行业科学家。

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.
