Acidity, defined as pH, is a central component of aqueous chemistry. In the atmosphere, the
acidity of condensed phases (aerosol particles, cloud water, and fog droplets) governs the …

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 …

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 …

Climate change and air pollution are critical environmental issues both in the here and now
and for the coming decades. A recent OECD report found that unless action is taken, air …

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 …

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 …

Atmospheric brown carbon (BrC) is a collective term for light absorbing organic compounds
in the atmosphere. While the identification of BrC and its formation mechanisms is currently …

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 …

We deployed a High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS)
and an Aerosol Chemical Speciation Monitor (ACSM) to characterize the chemical …

Brown carbon (BrC) consists of those organic compounds in atmospheric aerosols that
absorb solar radiation and may play an important role in planetary radiative forcing and …
