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 …

Secondary organic aerosol (SOA) produced by atmospheric oxidation of primary emitted
precursors is a major contributor to fine particulate matter (PM2. 5) air pollution worldwide …

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 …

Multiphase chemistry plays a vital role in the Earth system, climate, and health. Chemical
reactions, mass transport, and phase transitions between gases, liquids, and solids are …

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 …

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 …

Winter has the worst air pollution of the year in the megacity of Beijing. Despite extensive
winter studies in recent years, our knowledge of the sources, formation mechanisms and …

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 …

Progress has been made over the past decade in predicting secondary organic aerosol
(SOA) mass in the atmosphere using vapor pressure-driven partitioning, which implies that …
