A convective–radiative propagation model for wildland fires

International journal of wildland fire, 2020
The ‘Balbi model’ is a simplified steady-state physical propagation model for surface fires that considers radiative heat transfer from the surface area of burning fuel particles as well as from the flame body.

Mutagenicity and Lung Toxicity of Smoldering vs. Flaming Emissions from Various Biomass Fuels: Implications for Health Effects from Wildland Fires

Environmental Health Perspectives, 2018
Background: The increasing size and frequency of wildland fires are leading to greater potential for cardiopulmonary disease and cancer in exposed populations; however, little is known about how the types of fuel and combustion phases affect these ...

Multimodal Wildland Fire Smoke Detection

CoRR, 2022
Research has shown that climate change creates warmer temperatures and drier conditions, leading to longer wildfire seasons and increased wildfire risks in the United States. These factors have in turn led to increases in the frequency, extent, and severity of wildfires in recent years.

Wildland firefighter resources shortage in the United States;

Biodiversidade Brasileira, 2019
The United States (US) has a wildland fire resources shortage. During peak fire season, the US struggles to fill fire leadership and support positions to manage the 68,000 wildland fires that occur on an annual basis.
