Wildfires are associated with increased emergency department visits for anxiety disorders in the western United States

As wildfires increasingly impact the global economy and public health, understanding their effects is crucial. Particularly, the relationship between wildfires and anxiety disorders remains unclear. In this study, we explore this association by analyzing 1,897,865 emergency…

Ingesting GOES-16 fire radiative power retrievals into Warn-on-Forecast System for Smoke (WoFS-Smoke)

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…

Current and future patterns of global wildfire based on deep neural networks

Global climate change and extreme weather has a profound impact on wildfire, and it is of great importance to explore wildfire patterns in the context of global climate change for wildfire prevention and management. In this paper, a wildfire spatial prediction model based on…

Wildfire smoke exposure during SARS-CoV-2 vaccination impairs immunity via natural killer cell derived IL-13

Rationale: Wildfires are increasing in intensity, duration, and frequency with smoke plums affecting the lives of millions over large geographic areas. The immune modulatory effects of wildfire smoke are unclear. We previously showed that a major wildfire smoke component, ozone…

Investigating the spatial and temporal limitations for remote sensing of wildfire smoke using satellite and airborne imagers during FIREX-AQ

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…

Incorporating an interactive fire plume-rise model in the DOE's Energy Exascale Earth System Model Version 1 (E3SMv1) and examining aerosol radiative effect

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…

Emission factors from wildfires in the western US: an investigation of burning state, ground versus air, and diurnal dependencies during the FIREX-AQ 2019 campaign

Emission factors (EFs) are crucial in understanding the effects of wildfire emissions on air quality. We examined the variability of EFs of three wildfires (Nethker, Castle, and 204 Cow) during the 2019 Western US wildfire season using the Aerodyne Mobile Laboratory (AML) and…

Radiative transfer effects in natural convection above fires

This paper describes the results of examining the influence of radiative heat transfer on turbulent natural convection above fires in an atmosphere of constant potential temperature, under both the 'opaque' and 'transparent' approximations. It turns out that on the basis of the…

Fire whirlwinds in the laboratory

[Excerpted from text] Most experienced firefighters have encountered fire whirlwinds. These whirls, or "fire devils" as they are sometimes called, range in size from small twisters a foot or two in diameter up to violent whirls equal to small tornadoes in size and intensity.…

Exposure to smoke from wildfire, prescribed, and agricultural burns among at-risk populations across Washington, Oregon, and California

Wildfires, prescribed burns, and agricultural burns all impact ambient air quality across the Western U.S.; however, little is known about how communities across the region are differentially exposed to smoke from each of these fire types. To address this gap, we quantify smoke…

Strategic fire zones are essential to wildfire risk reduction in the western United States

Background: Over the last four decades, wildfires in forests of the continental western United States have significantly increased in both size and severity after more than a century of fire suppression and exclusion. Many of these forests historically experienced frequent fire…
