Influence of fire characteristics on the associations between smoke PM2.5 exposure and acute cardiorespiratory health events

Environment International
Background: Wildland fire smoke is a significant source of PM2.5 pollution in the western United States, with varying chemical composition and toxicity depending on fire characteristics. Methods: We analyzed emergency department and urgent care visits in

Field measurements of trace gases emitted by prescribed fires in southeastern US pine forests using an open-path FTIR system [PDF]

Atmospheric Chemistry and Physics, 2014
We report trace-gas emission factors from three pine-understory prescribed fires in South Carolina, US measured during the fall of 2011. The fires were more intense than many prescribed burns because the fuels included mature pine stands not subjected to

Study of Damage to Shutters Exposed to a Vegetation Fire: Definition of Vulnerability Thresholds

Fire and Materials, Volume 50, Issue 8, Page 941-954, December 2026.
ABSTRACT This study examines the fire behavior of wooden, PVC, and aluminum shutters through laboratory and large‐scale experiments. Laboratory tests were conducted using a cone calorimeter to assess the ignitability of the PVC and wooden shutters, focusing on the critical heat flux of ignition, ignition time and critical Flux Time Product ( FTP ...

Impact of Wildfire‐Emitted Black Carbon on Snowmelt Across Western North America

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract Wildfires are a major source of black carbon (BC) and their increasing frequency and intensity have enhanced BC deposition onto snowpack across western North America, which accelerates snowmelt and triggers multiple feedbacks that can substantially alter atmospheric composition and regional hydrology. Using the Weather Research and Forecasting

Geographical Distribution of Exposure to Fires in the United States Between 2004 and 2023

GeoHealth, Volume 10, Issue 11, November 2026.
Abstract Fire activity is increasing across the United States. Proximity to fires poses health risks beyond smoke exposure including injury, mental health impacts, and contamination of water and soil. However, the predominance of smoke‐focused studies has contributed to public health strategies centered on mitigating smoke exposure.

Modeling Multiple-Core Updraft Plume Rise for an Aerial Ignition Prescribed Burn by Coupling Daysmoke with a Cellular Automata Fire Model

Atmosphere, 2012
Smoke plume rise is critically dependent on plume updraft structure. Smoke plumes from landscape burns (forest and agricultural burns) are typically structured into “sub-plumes” or multiple-core updrafts with the number of updraft cores depending on ...
