Background: The record number of wildfires in the United States in recent years has led to an increased focus on developing tools to accurately forecast their impacts at high spatial and temporal resolutions. Aims: The Warn-on-Forecast System for Smoke (WoFS-Smoke) was developed…

Starting from point sources, wildfire smoke is important in the global aerosol system. The ability to characterize smoke near-source is key to modeling smoke dispersion and predicting air quality. With hemispheric views and 10-min refresh, imagers in Geostationary (GEO) orbit…

The vertical distribution of biomass burning aerosol (BBA) is important in regulating their impacts on weather and climate. The plume-rise process affects the injection height of BBA and interacts with the air parcel lifting and cloud processes. However, these processes are not…

A 1.3 hectare field containing hawthorn and alder was burned in April 1973. Post-burn analysis of 20 hawthorns and 20 alders determined the fire susceptibility of these species. Of those sampled, 80 percent of the trees less than 3 centimeters in basal diameter were killed. The…

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 more to the choice of emission…
