Proton-transfer-reaction mass spectrometry (PTR-MS) has been widely used to study the
emissions, distributions, and chemical evolution of volatile organic compounds (VOCs) in …

Background: Secondary organic aerosols (SOAs) formed from anthropogenic or biogenic
gaseous precursors in the atmosphere substantially contribute to the ambient fine particulate …

Organic-aerosol phase partitioning (volatility) and oxidative aging are inextricably linked in
the atmosphere because partitioning largely controls the rates and mechanisms of aging …

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 …

Carbonaceous particulate matter (PM), comprising black carbon (BC), primary organic
aerosol (POA) and secondary organic aerosol (SOA, from atmospheric aging of precursors) …

Anthropogenic volatile organic compounds (AVOCs) often dominate the urban atmosphere
and consist to a large degree of aromatic hydrocarbons (ArHCs), such as benzene, toluene …

Organic gases undergoing conversion to form secondary organic aerosol (SOA) during
atmospheric aging are largely unidentified, particularly in regions influenced by …

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 …

Peroxide-containing highly oxygenated molecules (HOMs) are formed upon ozonolysis of
terpenes emitted from the biosphere and are expected to be a major driving force for the …

Chamber oxidation experiments conducted at the Fire Sciences Laboratory in 2016 are
evaluated to identify important chemical processes contributing to the hydroxy radical (OH) …
