Title: Characterizing Particulate Matter Emissions by Wildland Fires Relevant to Visibility Impairment and PM Non-Attainment

Project Proposal Abstract: The occurrence of wildland fires results in substantial emissions of air pollutants. These emissions have resulted in increased conflicts with the need to attain air quality standards, especially for particulate matter (PM) and visibility, as mandated by the Clean Air Act. To manage these conflicts, there is a pressing need for emission factors for PM mass and its optical cross-sections and PM characteristics as function of wildland fuels and combustion conditions. The proposed research builds on previous and ongoing work in order to provide resource managers and planners with information on PM emissions that will improve their capability to safely and effectively use prescribed fire while minimizing adverse effects on air quality. We will undertake a series of laboratory and field experiments using novel instrumentation to obtain the parameters and understanding needed to model the influence of wildland fires on visibility impairment and PM nonattainment. Benefits of the proposed work, that can directly be utilized to improve smoke and regional haze models, are an improved understanding of optical, physical, and chemical properties of PM emitted by wildland fires, PM and optical emission rates for wildland fires, and a new and improved method for quantifying EC and OC emissions from wildland fires with high time resolution.
