In this webinar, RMRS research physical scientist Shawn Urbanski and fire ecologist Duncan Lutes will discuss the current state of the science on wildland fire smoke emissions.

State of the science on wildland fire emissions

Science Spotlights Posted on: August 20, 2020
We evaluated current scientific literature, datasets, and models to assess the state of the science on wildland fire emissions. The assessment evaluates current knowledge regarding the composition, intensity, and drivers of emissions and discusses the crucial gaps in our understanding of emissions.

Proceedings of the Fire Continuum-Preparing for the future of wildland fire; 2018 May 21-24; Missoula, MT

Publications Posted on: July 22, 2020
The Fire Continuum Conference, co-sponsored by the Association for Fire Ecology and the International Association of Wildland Fire, was designed to cover both the biophysical and human dimensions aspects of fire along the fire continuum. This proceedings includes many of topics covered during the conference - including pre-fire planning and management, strategies during an incident, and post-fire effects and management options.

Wildland fire in ecosystems: effects of fire on air

Publications Posted on: June 22, 2020
This state-of-knowledge review about the effects of fire on air quality can assist land, fire, and air resource managers with fire and smoke planning, and their efforts to explain to others the science behind fire-related program policies and practices to improve air quality.

National strategic plan: modeling and data systems for wildland fire and air quality.

Publications Posted on: June 22, 2020
This strategic plan is a technical discussion of the implementation and development of models and data systems used to manage the air quality impacts of wildland and prescribed fires. Strategies and priorities in the plan were generated by the Express Team (chartered by the National Wildfire Coordinating Group) and a diverse group of 86 subject matter experts who attended a national planning workshop.

Assessing values of air quality and visibility at risk from wildland fires.

Publications Posted on: June 22, 2020
To assess values of air quality and visibility at risk from wildland fire in the United States, we generated a 40-year database that includes twice daily values of wind, mixing height, and a ventilation index that is the product of windspeed and mixing height. The database provides the first nationally consistent map of surface wind and ventilation index. In addition, it is the longest climate record of mixing height in the country.

Wildland fire emission factors in North America: synthesis of existing data, measurement needs and management applications

Publications Posted on: March 11, 2020
Field and laboratory emission factors (EFs) of wildland fire emissions for 276 known air pollutants sampled across Canada and the US were compiled. An online database, the Smoke Emissions Repository Application (SERA), was created to enable analysis and summaries of existing EFs to be used in smoke management and emissions inventories.

The Missoula Fire Lab Wildfire Emission Inventory

Science Spotlights Posted on: April 15, 2019
Wildfires are a major source of fine particulate matter pollution (PM2.5) in the United States and can have substantial impacts on public health. In addition to acute pollution episodes, wildfires can have a marginal effect on air quality at significant distances from the source, presenting significant challenges to air regulators’ efforts to meet National Ambient Air Quality Standards. Improved emission estimates are needed to quantify the contribution of wildfires to air pollution and thereby inform decision-making activities related to the control and regulation of anthropogenic air pollution sources.

Guidelines for evaluating air pollution impacts on wilderness within the Rocky Mountain Region: Report of a workshop, 1990

Publications Posted on: August 01, 2018
This document is the product of an ongoing effort begun at a 4-day workshop sponsored by the Rocky Mountain Region of the USDA Forest Service, held in December 1990 in Estes Park, Colorado. Workshop participants gathered in groups to work on pollution impacts in three specific areas: aquatic ecosystems; terrestrial ecosystems; and visibility.

Wilderness science in a time of change conference-Volume 5: Wilderness ecosystems, threats, and management; 1999 May 23-27; Missoula, MT

Publications Posted on: August 01, 2018
Forty-six papers are presented on the nature and management of threats to wilderness ecosystems. Five overview papers synthesize knowledge and research on wilderness fire, recreation impacts, livestock in wilderness, nonnative invasive plants, and wilderness air quality.
