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

Secondary organic aerosol (SOA) is formed from the atmospheric oxidation of gas-phase
organic compounds leading to the formation of particle mass. Gasoline-and diesel-powered …

A gap in emission inventories of urban volatile organic compound (VOC) sources, which
contribute to regional ozone and aerosol burdens, has increased as transportation …

China experienced severe haze pollution in January 2013. Here we have a detailed
characterization of the sources and evolution mechanisms of this haze pollution with a focus …

Abstract Fine particle pollution, PM2. 5, is associated with increased risk of death from
cardiorespiratory diseases. A multidecadal shift in the United States (US) PM2. 5 …

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 …

To investigate the seasonal characteristics of submicron aerosol (PM1) in Beijing urban
areas, a high‐resolution time‐of‐flight aerosol‐mass‐spectrometer (HR‐ToF‐AMS) was …

We investigate the sources, chemical composition, and spectral properties of light-absorbing
organic aerosol extracts (ie, brown carbon, or BrC) in the Los Angeles (LA) Basin during the …

Atmospheric particulate matter (PM) pollution has become a major health threat
accompanying the rapid economic development in China. For decades, filter-based offline …

Particle pH is a critical but poorly constrained quantity that affects many aerosol processes
and properties, including aerosol composition, concentrations, and toxicity. We assess PM1 …
