This project will characterize the physical and chemical properties of carbonaceous particles generated in the combustion of solid fuels. Particles from these sources have received less attention than from other sources, but are estimated to account for roughly 2/3 of the global emissions. The project will involve a mixture of laboratory and field studies that include examining the emissions from fuels in various stages of combustion using a two-stage pyrolytic reactor developed in this study, analyzing samples collected from locations for which solid fuels are widely used (primarily third world Asian countries) to compare with the laboratory results, and development of schemes for incorporation of these results into models.The work plan includes a broad goal to improve understanding of international air-quality issues for students and the general public. Observations and data analysis will be incorporated into a class that will include discussion and application of statistical methods. The concept of emission inventories will be used along with a database query model as a tool to demonstrate the impacts of various types and locations of emissions on atmospheric particulate content. This model will also be made available as a web-based tool. Guest lecturers, with expertise on international air quality issues, will be invited to the PI's institution to interact with students in the department and with members of the wider university community. Two graduate students will receive training under this program. This research will lead to better representation of carbon-containing particles in chemical transport models. Links between the fields of combustion and atmospheric chemistry will be improved, and collaborations between international researchers and non-profit organizations will be enhanced. The facility for generating combustion-based particles will be useful to the community for calibration and instrument intercomparison.

该项目将表征固体燃料燃烧中产生的碳质颗粒的物理和化学性质。 与其他来源相比，这些来源的颗粒物受到的关注较少，但据估计约占全球排放量的 2/3。 该项目将涉及实验室和现场研究的结合，包括使用本研究中开发的两级热解反应器检查不同燃烧阶段的燃料排放，分析从广泛使用固体燃料的地点（主要是第三世界亚洲国家）收集的样本，以与实验室结果进行比较，以及制定将这些结果纳入模型的计划。该工作计划包括一个广泛的目标，以增进对国际的了解 学生和公众的空气质量问题。 观察和数据分析将纳入一门课程，其中包括统计方法的讨论和应用。 排放清单的概念将与数据库查询模型一起使用，作为展示各种类型和地点的排放对大气颗粒物含量影响的工具。 该模型还将作为基于网络的工具提供。 具有国际空气质量问题专业知识的客座讲师将被邀请到PI的机构与该系的学生以及更广泛的大学社区的成员进行互动。 两名研究生将接受该计划的培训。 这项研究将更好地表示化学输运模型中的含碳颗粒。 燃烧和大气化学领域之间的联系将得到改善，国际研究人员和非营利组织之间的合作也将得到加强。 用于生成基于燃烧的颗粒的设施将有助于社区进行校准和仪器比对。
