Black carbon is a byproduct of incomplete combustion of hydrocarbons and it has attracted
widespread attention in various fields such as atmospheric chemistry, climate change, and …

Fine-particle pollution associated with high sulfate and secondary organic aerosol (SOA)
contents still occurs in winter, despite considerable reductions in precursor emissions in …

Smoke from vegetation fires affects air quality, atmospheric cycling, and the climate in the
Amazon rain forest. A major unknown has remained the quantity of long-range transported …

Aerosol over the remote southeastern Atlantic is some of the most sunlight-absorbing
aerosol on the planet: the in situ free-tropospheric single-scattering albedo at the 530 nm …

Incomplete combustion of fossil fuels and biomass burning emit large amounts of soot
particles into the troposphere. The condensation process is considered to influence the size …

Refractive indices (RI) of particles are important in determining their radiative forcing. We
measured optical coefficients of particles classified according to their aerodynamic diameter …

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

While gas-phase reactions are well established to have significant impacts on the mass
concentration, chemical composition, and optical properties of secondary organic aerosol …

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 …

Atmospheric particles play critical roles in climate. However, significant knowledge gaps
remain regarding the vertically resolved organic molecular-level composition of atmospheric …
