RxCADRE 2012: Large burn smoke plume photographs and videos

Datasets Posted on: December 30, 2020
These data include time lapse JPEG and CR2 format photographs, taken every 5 seconds, as well as MTS videos from burns of the 2012 Prescribed Fire Combustion and Atmospheric Dynamics Research Experiment (RxCADRE) at Eglin Air Force Base, Florida. Images are provided from five cameras located around the fire perimeter at various distances for each burn, taken in November 2012.

Know Your Smoke: Updated Smoke Modeling Tool Estimates Higher Particulate Emissions From Wildfire Than Previously Predicted

Documents and Media Posted on: November 12, 2020
New emission factor updates to FOFEM will allow land managers to estimate emissions of hazardous air pollutants, which may be combined with ambient monitoring to assess fire fighter exposure. Document Type: Other Documents

Know your smoke

Events Posted on: October 06, 2020
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.

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.

Smoke management guide for prescribed and wildland fire: 2001 edition.

Publications Posted on: June 22, 2020
The National Wildfire Coordinating Group's (NWCG) Fire Use Working Team has assumed overall responsibility for sponsoring the development and production of this revised Smoke Management Guide for Prescribed and Wildland Fire (the "Guide").

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.

An evaluation of wildland fire smoke sensors

Projects Posted on: April 19, 2019
In a collaboration with the US Environmental Protection Agency (EPA), the Wildland Fire Sensor Challenge was conducted to solicit and evaluate next-generation air measurement technology in pursuit of an easy to deploy, reliable, and accurate on-demand smoke monitoring network. During the initial phase of the challenge, three prototype systems were identified for further development and testing. Second generation sensors will be evaluated by the USFS/EPA research team in spring 2019.

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.
