Estimates of Wildland Fire Emissions

摘要: Wildland fire missions can significantly affect regional and global air quality, radiation, climate, the carbon cycle. A fundamental yet challenging prerequisite to understanding environmental effects is accurately estimate emissions. This chapter describes analyzes emission calculations. Various techniques (field measurements, empirical relations, modeling, remote sensing) obtain fuel properties are first reviewed. calculation of emissions across continental U.S. then illustrated. In this calculation, an approach recently developed based on high-resolution types from satellite sensing used for loading factors. The burning information obtained a historical dataset collected by multiple governmental agencies. show large spatial temporal variability. Finally, uncertainties in estimates examined comparing with another method using traditional AP-42 Table loading. Emissions mostly reduced western U.S., but increased eastern coastal regions. perspective future research given.
