Multiphase and heterogeneous photochemistry is an emerging component of atmospheric
and air pollution research. It is primarily driven by reactions of photochemically produced …

Multiphase chemistry occurs between chemicals in different atmospheric phases, typically
involving gas–solid and gas–liquid interactions. The importance of atmospheric multiphase …

The lifecycle of black carbon (BC)-containing particles from biomass burns is examined
using aircraft and surface observations of the BC mixing state for plume ages from∼ 15 min …

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 …

Aqueous-phase reactions of α-dicarbonyls with ammonium or amines have been identified
as important sources of secondary brown carbon (BrC). However, the identities of most …

We investigate the chemical composition of organic light-absorbing components, also
known as brown carbon (BrC) chromophores, formed in a proxy of anthropogenic secondary …

The formation of secondary brown carbon (BrC) is chemically complex, leading to an
unclear relationship between its molecular composition and optical properties. Here, we …

Wildfires are a major source of biomass burning aerosol to the atmosphere, with their
incidence and intensity expected to increase in a warmer future climate. However, the …

In recent years, carbonaceous aerosols (CA) have been recognized as a significant
contributor to the concentration of particles smaller than 2.5 μm (ie, PM 2.5), with a negative …

The light-absorbing organic aerosol (OA) constitutes an important fraction of absorbing
components, counteracting major cooling effect of aerosols to climate. The mechanisms in …
