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

该项目包括在2013年夏季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（IVOCs）和半挥发性有机化合物（SVOCs）。IVOCs和SVOCs可能是二次有机气溶胶形成和演化过程中的重要物种，这是SOAS的主要研究重点，但它们受到的约束很差，而且无法通过常用技术进行常规的实时测量。将该仪器部署到SOAS地面场址将弥补有机物种库存测量方面的空白，并有助于总体碳核算。这些测量可能有助于实现SOAS的若干科学目标，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。该奖项将支持一名研究生进行测量，该研究生将在开展大气化学实地工作中获得宝贵的经验，与来自许多不同机构的研究人员（包括政府和行业科学家）合作。

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.
