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.

题目：“开放路径FTIR测量生物质燃烧排放”PI: Robert Yokelson，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。生物质火灾释放的大多数化学物质都具有充分的反应性，在大气中没有充分混合。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，火灾排放和烟羽的排放处理差异很大。本项目侧重于使用开放式傅立叶变换红外仪器（OP-FTIR）测量痕量气体化学物质的烟雾排放特征。OP-FTIR光谱仪器将在蒙大拿大学的火灾研究实验室中运行，并将测量来自特定燃料生物质火灾的气体产物。该仪器将进行修改和测试，以便在飞机平台上部署，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对生物质火灾引起的痕量气体排放的估计，并将扩大在烟雾中识别和测量的化合物范围。atm - 9631219
