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

Black carbon (BC) is functionally defined as the absorbing component of atmospheric total
carbonaceous aerosols (TC) and is typically dominated by soot-like elemental carbon (EC) …

Partitioning of mineral dust, pollution, smoke, and mixtures using remote sensing techniques
can help improve accuracy of satellite retrievals and assessments of the aerosol radiative …

The absorption Ångström exponent (AAE) of externally mixed black carbon (BC Ext), or BC
internally mixed with non-absorbing material (BC Int), is often used to determine the …

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 …
