This project will implement fast particle size distributions measurements during the 4th Fire Lab at Missoula Experiment (FLAME IV) Study. The measurements will be made with a Fast Mobility Particle Sizer (FMPS) that is (1) capable of measuring the size range of interest for fresh smoke aerosols, (2) has fast time response that will be useful for all burns, and (3) is capable of measuring high concentrations. These are all characteristics of the aerosol produced by biomass burns in the FLAME experiments, particularly stack burn experiments of relatively short duration (minutes to tens of minutes from ignition to flame out and smoldering). The measurements will be complementary to those of several other investigators that include ice nuclei and evolution of secondary organic aerosols from the burn emissions. The research will help to elucidate fundamental physicochemical properties of biomass smoke, important to health and climate impacts of smoke aerosols.The project is a unique collaboration between private sector and academic partners that has potential to lead to further developments in this arena. Broader impacts center on the continuation of FLAME collaborations begun a decade ago between the principal investigator and the other investigators on the project. Although students are not directly supported, it is anticipated that informal learning opportunities and collaborations with students working as part of the FLAME study will develop. Moreover, results to date from the principal investigator's research and work activities have been successfully integrated into the classroom in his adjunct faculty position at Front Range Community College and into seminars presented at regional air quality meetings and at nearby institutions of higher learning. The project will enhance collaborations within the regional air quality research and education community.

该项目将在米苏拉第四次火灾实验室实验 (FLAME IV) 研究期间实施快速粒度分布测量。测量将使用快速移动粒径分析仪 (FMPS) 进行，该测量仪 (1) 能够测量新鲜烟雾气溶胶的相关尺寸范围，(2) 具有对所有烧伤有用的快速时间响应，并且 (3) ）能够测量高浓度。这些都是FLAME实验中生物质燃烧产生的气溶胶的特征，特别是持续时间相对较短的烟囱燃烧实验（从点火到熄火和阴燃几分钟到几十分钟）。这些测量结果将与其他几位研究人员的测量结果相补充，包括冰核和燃烧排放产生的二次有机气溶胶的演变。该研究将有助于阐明生物质烟雾的基本物理化学特性，这对烟雾气溶胶的健康和气候影响非常重要。该项目是私营部门和学术合作伙伴之间的独特合作，有潜力推动这一领域的进一步发展。更广泛的影响集中在该项目的首席研究员和其他研究人员之间十年前开始的 FLAME 合作的延续上。尽管学生没有得到直接支持，但预计将发展非正式学习机会以及与参与 FLAME 研究的学生的合作。此外，迄今为止，首席研究员的研究和工作活动的成果已成功融入他在 Front Range 社区学院兼职教职的课堂中，以及在地区空气质量会议和附近高等教育机构举办的研讨会中。该项目将加强区域空气质量研究和教育界的合作。
