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.

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

Publications Posted on: August 01, 2018
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.

Fire and Smoke Model Evaluation Experiment (FASMEE): Modeling gaps and data needs

Publications Posted on: July 20, 2017
Fire and smoke models are numerical tools for simulating fire behavior, smoke dynamics, and air quality impacts of wildland fires. Fire models are developed based on the fundamental chemistry and physics of combustion and fire spread or statistical analysis of experimental data (Sullivan 2009). They provide information on fire spread and fuel consumption for safe and efficient prescribed (Rx) burning and wildfire suppression.

Airborne characterization of smoke marker ratios from prescribed burning

Publications Posted on: July 20, 2017
A Particle-Into-Liquid Sampler - Total Organic Carbon (PILS-TOC) and fraction collector system was flown aboard a Twin Otter aircraft sampling prescribed burning emissions in South Carolina in November 2011 to obtain smoke marker measurements.

Valuing morbidity effects of wildfire smoke exposure from the 2007 Southern California wildfires

Publications Posted on: October 07, 2016
This study estimated the economic costs associated with morbidity from the wildfires that occurred in 2007 in southern California. We used the excess number of hospital admissions and emergency department visits to quantify the morbidity effects and used medical costs to estimate the economic impact.

Social media approaches to modeling wildfire smoke dispersion: spatiotemporal and social scientific investigations

Publications Posted on: August 18, 2016
Wildfires have significant effects on human populations, economically, environmentally, and in terms of their general wellbeing. Smoke pollution, in particular, from either prescribed burns or uncontrolled wildfires, can have significant health impacts.

Lichens as bioindicators of air quality

Publications Posted on: July 05, 2016
This report is the result of a workshop held in Denver, Colorado on April 9-11, 1991. It summarizes the current literature and techniques for using lichens to monitor air quality.

Soils [Chapter 5]

Publications Posted on: May 12, 2016
This report describes the soils of the Lost Lake, West Glacier Lake, and East Glacier Lake watersheds of GLEES and presents the methods used in conducting both the field and laboratory work. In addition, general statements about the nature of the mapping units used in making the soil maps are provided.
