Surfactants are surface-active molecules or ions that can often be found at the surface of
atmospheric aerosol particles. Some surfactants, such as biomolecules in marine aerosol …

Atmospheric chemists have historically treated leaves as inert surfaces that merely emit
volatile hydrocarbons. However, a growing body of evidence suggests that leaves are …

Secondary organic aerosols (SOAs) can exist in liquid, semi-solid, or amorphous solid
states. Chemical transport models (CTMs), however, usually assume that SOA particles are …

Phenols emitted from biomass burning contribute significantly to secondary organic aerosol
(SOA) formation through the partitioning of semivolatile products formed from gas-phase …

Different populations of aerosol are constantly mixed throughout the atmosphere. Large-
scale models often assume no particle–particle mixing or fast mixing among aerosol …

Free tropospheric aerosol particles have important but poorly constrained climate effects
due to transformations of their physicochemical properties during long-range transport. In …

Evidence has accumulated that secondary organic aerosols (SOAs) exhibit complex
morphologies with multiple phases that can adopt amorphous semisolid or glassy phase …

Accurate predictions of chemical lifetime, ie, oxidation timescale and change in the mass of
organic aerosols (OAs) in atmospheric models, are critical to quantify the impacts of OA on …

Secondary organic aerosols (SOA) are fine particles in the atmosphere, which interact with
clouds, radiation and affect the Earth's energy budget. SOA formation involves chemistry in …

Observed surface organic aerosols (OA) concentrations slightly increased in the western US
(WUS) but significantly decreased in the eastern US (EUS) in summer, and continuously …
