Abstract Wildfires are increasing in frequency and intensity, strongly influencing both regional air quality and the Earth's radiation budget via their aerosol emissions. Relying on an unparalleled observational data set from the 2019 NOAA/NASA FIREX‐AQ campaign, this study quantifies the direct radiative …

The Global Ensemble Forecast System (GEFS) version 12 has been operational at the National Centers for Environmental Prediction since September 2020, with GEFS-Aerosols serving as its global aerosol forecasting member. In 2023, GEFS-Aerosols was upgraded to version 12.3 in operations, incorporating improvements …

Abstract The 2020 wildfires caused widespread elevated fine particulate matter (PM 2.5 ) concentrations across the western U.S. The Colorado Front Range experienced multiple smoke episodes from nearby fires and fires hundreds of kilometers away. Multiple days (88 total) with elevated PM …

Smoke from spring boreal wildfires increasingly impacts eastern North America, exposing breeding birds to hazardous air pollution that may impact reproductive outcomes. Using data collected in 2018-2025 from 70,979 monitored nests of four widespread cavity-nesting songbirds, we found strong evidence that smoke …

Abstract The intensification of wildland fires across portions of Canada in early June 2023 led to significant smoke transport into the eastern United States, resulting in poor air quality and reduced visibility. Significant degradation of air quality was evident from PM 2.5 …

Abstract Fire radiative power (FRP) detection of wildland fires is important in calculating a variety of variables, such as smoke emissions, which are necessary for fire weather and air quality simulations. FRP is derived from satellite observations of radiative energy emitted by …
