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

Aerosols are important atmospheric constituents with significant impacts on both regional air
quality and the global climate and environment. Aerosol effects on radiation, clouds and …

Organic carbon (OC) accounts for a large fraction of atmospheric aerosol and has profound
effects on air quality, atmospheric chemistry, and climate forcing. The molecular composition …

Black carbon aerosol plays a unique and important role in Earth's climate system. Black
carbon is a type of carbonaceous material with a unique combination of physical properties …

Several recent observational studies have shown organic carbon aerosols to be a significant
source of absorption of solar radiation. The absorbing part of organic aerosols is referred to …

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 …

Aerosols affect Earth's climate both directly and indirectly, which is the largest uncertainty in
the assessment of radiative forcings affecting anthropogenic climate change. The standard …

Light-absorbing organic carbon (ie, brown carbon or BrC) in the atmospheric aerosol has
significant contribution to light absorption and radiative forcing. However, the link between …

Carbonaceous aerosols affect the global radiative balance by absorbing and scattering
radiation, which leads to warming or cooling of the atmosphere, respectively. Black carbon is …
