Investigating the relationship between stakeholder opinion about wildfire management and landscape context using GIS [PDF]

open access: yes, 2006
Colorado residents living in the wildland urban interface (WUI) were asked about their perception of wildfire risk and their willingness-to-pay (WTP) for three fire management procedures: fuel reduction by thinning, fire suppression and prescribed fires.

Evaluation of WindNinja Simulations in Canyon Topography

open access: yesForecasting
This study describes a validation of the surface wind model WindNinja conducted over different types of complex terrain. The Weather Research and Forecasting model (WRF) 2 km output was used as input for our WindNinja simulations.

Historical Fire Regimes and Their Differential Responses to Driving Climatic Factors Across Ecoregions in the United States: A Tree-Ring Fire-Scar Analysis

open access: yesFire
Fire is a key driver of ecosystem dynamics under global change, and understanding its complex relationship with the climate system is crucial for regional wildfire risk management and the development of ecological adaptation strategies.

Charcoal evidence that rising atmospheric oxygen terminated Early Jurassic ocean anoxia

open access: yesNature Communications, 2017
Numerical models predict that during an oceanic anoxic event (OAE), increased organic carbon burial drives a rise in atmospheric oxygen leading to the event’s termination. Here, the authors present evidence suggesting that the Toarcian OAE was terminated

Can Satellite-Observed Wildfire Incidents Alone Project Next-Year State Transition? A Case Study in British Columbia, Canada Using a Physics-Regularized Conditional Categorical Generative Model [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Wildfire risk plays a critical role in natural disaster emergency response and climate change mitigation. Existing data-driven methods mainly focus on short-term wildfire forecasting (days to months), often relying on numerous driving factors and binary ...

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

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

Perceptions of Exposure and Mask Use in Wildland Firefighters

open access: yesToxics
Wildland firefighters are exposed to airborne particulates, polycyclic aromatic hydrocarbons (PAHs), and other hazardous substances. Respiratory protection is indicated, but information is lacking on the tasks and conditions for which mask wearing should
