The Smoke Emissions Repository Application (SERA) database is a compilation of field and laboratory emission factors of wildland fire across the United States and Canada. The SERA database facilitates the analysis and summary of existing emission...

A diversity of partners and interests, federal to private, came together to identify current challenges and research in the wildland fire and air quality impacts realm. Meeting management needs and the opportunity to learn from one another’s expert...

Shawn Urbanski, Research Scientist with the USDA Forest Service Rocky Mountain Research Station presented the latest research in emission factors. Emission factors are a key component to estimating emissions of trace gases and particulates from fire....

While the vast majority of carbon emitted by wildland fires is released as CO2, CO, and CH4, wildland fire smoke is nonetheless a rich and complex mixture of gases and aerosols. Primary emissions include significant amounts of CH4 and aerosol (organic...

In the US, wildfires and prescribed burning present significant challenges to air regulatory agencies attempting to achieve and maintain compliance with air quality regulations. Fire emission factors (EF) are essential input for the emission models...

The purpose of the workshop was for research scientists, air quality specialists, policy administrators, and others to present and discuss recent advances in research relating to estimation of emission factors for particulate matter (PM) and its...

Burning of agricultural waste residue is a common method of disposal when preparing land following crop harvest. This practice introduces volatile organic compounds, including polycyclic aromatic hydrocarbons (PAHs), into the atmosphere. This study...

In this paper we present the first early dry season (early June-early August) emission factor measurements for carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), nonmethane hydrocarbons (NMHC), and particulates with a diameter less than 2.5...
The WebFIRE application web site provides fast and complete access to the Agency's air emissions factors information. WebFIRE has replaced the software application, FIRE version 6.25 and the MS Access version of the database. The Factor...
Recent estimates of particulate production from forest fires in the United States have ranged from 500,000 to 54,000,000 tons annually. This has been due partly to disparities in estimates of fuel that is consumed during the combustion process, but...
Presentation to the 33rd Conference on Agricultural and Forest Meteorology/12th Fire and Forest Meteorology Symposium/Fourth Conference on Biogeosciences. This presentation focuses on emission factors for wildland fire fuels.
Particulate-matter emission factors and Byram's fire-intensity values were computed for experimental backfires in pine-litter and palmetto-gallberry fuels in the Southeast. The combined data for both fuel types were in reasonable agreement with...
A web page with information and access to the Deterministic and Empirical Assessment of Smoke's Contribution to Ozone (DEASCO3), Western Regional Air Partnership Fire Emissions Tracking System (WRAPFETS), and PMDETAIL.
This report characterizes smoke emissions from small-scale prescribed burns in southern California chaparral. In situ measurements of smoke emissions were made from 12 fires. Three replicate tests were performed in each of four distinct fuel and fire...
Biomass burning (BB) is a major source of black carbon (BC), but comparing BC content of different smoke-impacted air masses may be uncertain if different measurement techniques are used to quantify the BC, or if non-BC fractions influence a given...

Aerosol emissions from vegetation fires have a large impact on air quality and climate. In this study, we use published experimental data and different fitting procedures to derive dynamic particle number and mass emission factors (EFPN, EFPM) related...
While the vast majority of carbon emitted by wildland fires is released as CO2, CO, and CH4, wildland fire smoke is nonetheless a rich and complex mixture of gases and aerosols. Primary emissions include significant amounts of CH4 and aerosol (organic...
