Volatility and viscosity are important properties of organic aerosols (OA), affecting aerosol
processes such as formation, evolution, and partitioning of OA. Volatility distributions of …

Atmospheric organic aerosol (OA) has important impacts on climate and human health but
its sources remain poorly understood. Biogenic monoterpenes and sesquiterpenes are …

Organic nitrate chemistry is the primary control over the lifetime of nitrogen oxides (NO x) in
rural and remote continental locations. As NO x emissions decrease, organic nitrate …

The reaction of α-pinene with NO 3 is an important sink of both α-pinene and NO 3 at night in
regions with mixed biogenic and anthropogenic emissions; however, there is debate on its …

We evaluate monoterpene-derived peroxy radical (MT-RO 2) unimolecular autoxidation and
self-and cross-reactions with other RO 2 species in the GEOS-Chem global chemical …

Aerosol sulfate is a major component of submicron particulate matter (PM 1). Sulfate can be
present as inorganic (mainly ammonium sulfate, AS) or organosulfate (OS). Although OS is …

Secondary organic aerosol derived from isoprene epoxydiols (IEPOX-SOA) is thought to
contribute the dominant fraction of total isoprene SOA, but the current volatility-based …

The Southeast United States has experienced a different climate warming trend compared to
other places worldwide. Several hypotheses have been proposed to explain this trend, one …

Clouds are prevalent and alter fine particulate matter (PM 2.5) mass and chemical
composition. Cloud-affected satellite retrievals are subject to higher uncertainty and are …

The Fourier transform infrared (FTIR) spectra of fine particulate matter (PM 2.5) contain many
important absorption bands relevant for characterizing organic matter (OM) and obtaining …
