Open-Path FTIR Measurement Studies of Biomass Burning Emissions

美国国家科学基金会提案：ATM-9631219标题：“生物质燃烧排放的开放路径傅里叶变换红外测量”PI：罗伯特·约克尔森，蒙大拿大学化学系摘要生物质燃烧向区域和全球大气中注入了大量的微量气体。生物质火灾排放的大多数化学物质具有足够的反应性，在大气中不能很好地混合。此外，在单一火灾事件中，生物质燃烧的不同阶段以及不同类型的生物质植被的火灾排放和烟羽的排放处理也有很大差异。本项目的重点是利用开路傅里叶变换红外仪(OP-FTIR)测量微量气体化学物种的烟雾排放特征。OP-FTIR光谱仪器将在蒙大拿大学的火灾研究实验室运行，并将测量特定燃料生物质火灾的气体产物。该仪器将进行改装和测试，以便部署在飞机平台上，并用于大规模生物质火灾的地面研究。OP-FTIR光谱测量技术将改进生物质火灾造成的微量气体排放估计，并将扩大在烟雾中识别和测量的化合物的范围。自动柜员机-9631219

NSF Proposal: ATM-9631219 Title: "Open-path FTIR Measurement of Biomass Burning Emissions" PI: Robert Yokelson, University of Montana, Department of Chemistry Abstract Biomass burning injects significant amounts of trace gases into the regional and global atmosphere. Most of the chemical species emitted by biomass fires are sufficiently reactive and are not well-mixed in the atmosphere. In addition, fire emissions and emissions-processing of smoke plumes vary considerably at different stages of biomass combustion within a single fire event, and also, for distinct types of biomass vegetation. This project focuses on emissions characterization of smoke using an open path fourier transform infrared instrument (OP-FTIR) to measure trace gas chemical species. The OP-FTIR spectroscopic instrument will operate in the fire research laboratory at the University of Montana and will measure gaseous products from fuel-specific biomass fires. The instrument will be modified and tested for deployment on aircraft platforms and for ground-based studies of large-scale biomass fires. The OP-FTIR spectroscopic measurement technique will improve emissions estimates of trace gases due to biomass fires, and will expand the range of chemical compounds that are identified and measured in smoke.
