Comparisons of High Spatiotemporal Resolution Air Quality Modeling Frameworks for Prescribed Burning Simulations at a Military Base in the Southeastern United States

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 22, 28 November 2025.
Abstract High spatiotemporal resolution air quality modeling is essential for air quality impact assessments and decision‐making for prescribed burns. Accurate representation of the heterogeneous distribution of fuels and the structure of smoke plumes requires high‐resolution modeling frameworks.

Reconstructing Fire Progression from UAS Observations to Evaluate Bioaerosol Transport Sensitivity in Coupled Fire–Atmosphere Simulations

Fire
Bioaerosols released during wildland and prescribed fires may influence ecosystems, air quality, and microbial dispersal, yet their transport and deposition remain poorly understood.

Generative Algorithms for Wildfire Progression Reconstruction from Multi-Modal Satellite Active Fire Measurements and Terrain Height

Remote Sensing
Wildfire spread prediction models, including even the most sophisticated coupled atmosphere–wildfire models, diverge from observed wildfire progression during multi-day simulations, motivating the need for measurement-based assessments of wildfire state ...

Sensitivity of Simulated Fire‐Generated Circulations to Fuel Characteristics During Large Wildfires

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 6, 28 March 2024.
Abstract Coupled fire‐atmosphere models often struggle to simulate important fire processes like fire generated flows, deep flaming fronts, extreme updrafts, and stratospheric smoke injection during large wildfires. This study uses the coupled fire‐atmosphere model, WRF‐Fire, to examine the sensitivities of some of these phenomena to the modeled total ...

Coupled Atmosphere–Fire Modelling of Pyroconvective Activity in Portugal

Fire
This study investigates the physical interactions and between forest fires and the atmosphere, which often lead to conditions favourable to instability and the formation of pyrocumulus (PyCu). Using the coupled atmosphere–fire spread modelling framework,

The Short-Term Impacts of the 2017 Portuguese Wildfires on Human Health and Visibility: A Case Study

Fire
The frequency of extreme wildfire events (EWEs) is expected to increase due to climate change, leading to higher levels of atmospheric pollutants being released into the air, which could cause significant short-term impacts on human health (both for the ...

Interactions Between a High-Intensity Wildfire and an Atmospheric Hydraulic Jump in the Case of the 2023 Lahaina Fire

Atmosphere
On 8 August 2023, a grass fire that started in the city of Lahaina, Hawai’i, grew into the deadliest wildfire in the United States since 1918. This wildfire offers a unique opportunity to explore the impact of high heat output on an atmospheric hydraulic

Comment on Shamsaei et al. The Role of Fuel Characteristics and Heat Release Formulations in Coupled Fire-Atmosphere Simulation. Fire 2023, 6, 264

Fire
Accurate vertical distribution of fire-induced heat fluxes in the atmosphere is critical for realistic coupled fire–atmosphere simulations. In response to concerns raised by Shamsaei et al. (2023) regarding potential energy conservation issues in the WRF-
