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.

该项目将在米苏拉实验（FLAME IV）研究的第四个火灾实验室期间实施快速颗粒尺寸分布测量。将使用快速移动粒度仪（FMPS）进行测量，该粒度仪（1）能够测量新鲜烟雾气溶胶的目标尺寸范围，（2）具有快速时间响应，适用于所有烧伤，（3）能够测量高浓度。这些是FLAME实验中生物质燃烧产生的气溶胶的所有特征，特别是持续时间相对较短的烟囱燃烧实验（从点火到火焰熄灭和阴燃的几分钟到几十分钟）。这些测量将补充其他几个研究人员的测量，包括冰核和燃烧排放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至关重要。该项目是私营部门和学术合作伙伴之间的独特合作，有可能导致这一竞技场的进一步发展。更广泛的影响集中在FLAME合作的延续上，该合作始于十年前，主要研究者和该项目的其他研究者之间。虽然学生没有得到直接支持，但预计将发展非正式学习机会和与作为FLAME研究一部分的学生合作。此外，迄今为止，主要研究者的研究和工作活动的结果已成功地融入他在Front Range社区学院兼职教师职位的课堂，并在区域空气质量会议和附近的高等院校举办的研讨会中。该项目将加强区域空气质量研究和教育界的合作。
