Anthropogenic emissions and land use changes have modified atmospheric aerosol
concentrations and size distributions over time. Understanding preindustrial conditions and …

Light-absorbing carbonaceous aerosols (LACs), including black carbon and light-absorbing
organic carbon (brown carbon, BrC), have an important role in the Earth system via heating …

The evolution of organic aerosol (OA) and brown carbon (BrC) in wildfire plumes, including
the relative contributions of primary versus secondary sources, has been uncertain in part …

Emitted by numerous primary sources and formed by secondary sources, atmospheric
brown carbon (BrC) aerosol is chemically complex. As BrC aerosol ages in the atmosphere …

Lag Ba'Omer, a nationwide bonfire festival in Israel, was chosen as a case study to
investigate the influence of a major biomass burning event on the light absorption properties …

Emissions from biomass burning are a significant source of brown carbon (BrC) in the
atmosphere. In this study, we investigate the molecular composition of freshly emitted …

Particulate brown carbon (BrC) in the atmosphere absorbs light at subvisible wavelengths
and has poorly constrained but potentially large climate forcing impacts. BrC from biomass …

Light-absorbing components of atmospheric organic aerosols, which are collectively termed
“brown carbon”(BrC), are ubiquitous in the atmosphere. They affect absorption of solar …

Abstract Purpose of Review The direct radiative effect of brown carbon (BrC) absorption
predicated by climate-modeling studies is highly uncertain, with values ranging between+ …

To better understand the effects of wildfires on air quality and climate, it is important to
assess the occurrence of chromophoric compounds in smoke and characterize their optical …
