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 …

Multiple linkages connect air quality and climate change. Many air pollutant sources also
emit carbon dioxide (CO2), the dominant anthropogenic greenhouse gas (GHG). The two …

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 …

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 …

1. INTRODUCTION Atmospheric aerosols play a key role in the Earth's atmosphere.
Aerosols influence cloud formation and their lifetime, they affect the distribution and amount …

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 …

The mechanisms leading to the formation of secondary organic aerosol (SOA) are an
important subject of ongoing research for both air quality and climate. Recent laboratory …

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+ …
