Air quality impacts from wildfires have been dramatic in recent years, with millions of people
exposed to elevated and sometimes hazardous fine particulate matter (PM 2.5) …

Atmospheric ice‐nucleating particles (INPs) play a critical role in cloud freezing processes,
with important implications for precipitation formation and cloud radiative properties, and …

Emitted by numerous primary sources and formed by secondary sources, atmospheric
brown carbon (BrC) aerosol is chemically complex. As BrC aerosol ages in the atmosphere …

Massive Australian wildfires lofted smoke directly into the stratosphere in the austral summer
of 2019/20. The smoke led to increases in optical extinction throughout the midlatitudes of …

Abstract The NOAA/NASA Fire Influence on Regional to Global Environments and Air
Quality (FIREX‐AQ) experiment was a multi‐agency, inter‐disciplinary research effort to:(a) …

Biomass burning organic aerosol (BBOA) in the atmosphere contains many compounds that
absorb solar radiation, called brown carbon (BrC). While BBOA is in the atmosphere, BrC …

Wildfire smoke, consisting primarily of organic aerosols, has profound impacts on air quality,
climate and human health. Wildfire organic aerosol evolves over long-time photochemical …

Sub-Saharan Africa is a hotspot for biomass burning (BB)-derived carbonaceous aerosols,
including light-absorbing organic (brown) carbon (BrC). However, the chemically complex …

Wildfires are a substantial but poorly quantified source of tropospheric ozone (O3). Here, to
investigate the highly variable O3 chemistry in wildfire plumes, we exploit the in situ …

Biomass burning is the largest combustion-related source of volatile organic compounds
(VOCs) to the atmosphere. We describe the development of a state-of-the-science model to …
