Impact/Purpose:
Since biomass burning has been identified as an important contributor to the degradation of air quality, accurately characterizing fire emissions is important. We plan to use the results to improve the characterization of fires (spatial, temporal, and chemical) in air quality modeling systems.
Description:
The EPA estimates area burned and emissions from wildland fires, prescribed fires, grassland fires, and crop residue burning every three years for the National Emissions Inventory (NEI). For NEI and non-NEI years, different methods and datasets have been applied. To fully characterize the air quality (AQ) impacts of different fire types, a consistent method for inventories was developed and retrospectively applied. A multi-year reanalysis of fires from 2002 - 2017 was developed using the best available data and methods to estimate emission factors and fire activity. The new fire emissions estimates will be used in 2002-2017 CMAQ simulations for long-term AQ trend analysis and human health and ecological applications.Comparisons with existing EPA datasets will be presented.
