Prescribed fire is an important tool for maintaining the resilience of fire-dependent ecosystems. Despite broad recognition of its value, however, prescribed fire application in the western US has not been applied at the necessary levels. Past research...

Wildfires over the past 3 years have resulted in lengthy episodes of smoke inundation across major metropolitan areas in Australia, Brazil, and the United States. In 2020, air quality across the western United States reached and sustained extremely...
Wildfires are an important source of nitrous acid (HONO), a photolabile radical precursor, yet in situ measurements and quantification of primary HONO emissions from open wildfires have been scarce. We present airborne observations of HONO within...
The evolution of organic aerosol (OA) and brown carbon (BrC) in wildfire plumes, including the relative contributions of primary versus secondary sources, has been uncertain in part because of limited knowledge of the precursor emissions and the...
Peatlands play an important role as carbon pools, storing a third of the world's soil carbon. However, peatlands in Southeast Asia have suffered from depletion due to economic pressure and the demand for natural resources, often caused by land use...
The Western Wildfire Experiment for Cloud Chemistry, Aerosol Absorption, and Nitrogen (WE‐CAN) deployed the NSF/NCAR C‐130 aircraft in summer 2018 across the western U.S. to sample wildfire smoke during its first days of atmospheric evolution. We...
Fire has been a natural feature of the ecosystem for million years. Still, currently fire regimes have been increasingly altered by human activities and climate change, causing economic losses, air pollution, and environmental damage. In Brazil,...
Several studies have separately explored accumulation of the dominant fuels (grass, fine litter (<6 mm diameter) and coarse woody debris (CWD, 6-50 mm diameter)) in north Australian savannas. We report an analysis of two longitudinal datasets...
Biomass fires in Indonesia emit high levels of greenhouse gases and particulate matter, key contributors to global climate change and poor air quality in south-east Asia. In order to better understand the drivers of biomass fires across Indonesia over...
Wildland firefighters are exposed to health hazards including inhaling hazardous pollutants from the combustion of live and dead vegetation (smoke) and breathe soil dust, while working long shifts with no respiratory protection. This research brief...
