Chemical Processes in the Atmosphere V: The long term research objective of this research proposal is to elucidate the relative importance of chemical processes in the formation of gases and aerosols that have health, air quality and climate implications. In addition, our goal is to develop and apply new methods to the top-down measurement of “real world” anthropogenic emissions of Greenhouse Gases and other combustion emissions (SO2, NOx) to the atmosphere. In particular, we will be developing new methods and apply these methods for measurements of the emissions from large sources such as oil and gas facilities in Western Canada, landfills in Ontario and large ships that operate in populated areas. Finally we will continue our research into the measurement of chemical radicals and radical precursors and their vertical distribution in the lowest portion of the troposphere, as these species dominate the chemical processes occurring in the atmosphere.**

大气中的化学过程V：这项研究建议的长期研究目标是阐明化学过程在形成对健康、空气质量和气候有影响的气体和气溶胶方面的相对重要性。 此外，我们的目标是开发和应用新的方法，以自上而下的测量“真实的世界”人为排放的温室气体和其他燃烧排放（二氧化硫，氮氧化物）的大气。特别是，我们将开发新的方法，并将这些方法应用于测量加拿大西部的石油和天然气设施、安大略的垃圾填埋场和在人口稠密地区作业的大型船舶等大型来源的排放。 最后，我们将继续研究化学自由基和自由基前体的测量及其在对流层最低部分的垂直分布，因为这些物种主导着大气中发生的化学过程。
