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 …

This Review aims to summarize the current understanding of bulk tropospheric aqueous-
phase chemistry. Because a complete review of all developments in this area would be …

Secondary organic aerosol (SOA) accounts for a significant fraction of ambient tropospheric
aerosol and a detailed knowledge of the formation, properties and transformation of SOA is …

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 …

The acidity of aqueous atmospheric solutions is a key parameter driving both the partitioning
of semi-volatile acidic and basic trace gases and their aqueous-phase chemistry. In addition …

The Earth's atmosphere offers a striking contrast with other known planets by its rich organic
composition, which results almost exclusively from the presence of life on the planet. About …

Filter samples of secondary organic aerosols (SOA) generated from the ozone (O3)-and
hydroxyl radical (OH)-initiated oxidation of various biogenic (isoprene, α-pinene, limonene …

Brown carbon aerosol consists of light‐absorbing organic particulate matter with wavelength‐
dependent absorption. Aerosol optical extinction, absorption, size distributions, and …

A workshop was held in the framework of the ACCENT (Atmospheric Composition Change–
a European Network) Joint Research Programme on" Aerosols" and the Programme on" …
