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

The importance of organic aerosol particles in the environment has been long established,
influencing cloud formation and lifetime, absorbing and scattering sunlight, affecting …

Secondary organic aerosols (SOA) are a large source of uncertainty in our current
understanding of climate change and air pollution. The phase state of SOA is important for …

Severe haze events with exceedingly high-levels of fine aerosols occur frequently over the
past decades in the North China Plain (NCP), exerting profound impacts on human health …

Acid-catalyzed reactions between gas-and particle-phase constituents are critical to
atmospheric secondary organic aerosol (SOA) formation. The aerosol-phase state is thought …

Atmospheric aerosols, solid or liquid particles suspended in the atmosphere, range in size
from 1 nm to> 100 μm and come from a wide variety of sources. 1 As such, aerosols have a …

Secondary organic aerosol (SOA) accounts for a large fraction of submicron particles in the
atmosphere. SOA can occur in amorphous solid or semi-solid phase states depending on …

pH is a fundamental aerosol property that affects ambient particle concentration and
composition, linking pH to all aerosol environmental impacts. Here, PM 1 and PM 2. 5 pH …

Volatility and viscosity are important properties of organic aerosols (OA), affecting aerosol
processes such as formation, evolution, and partitioning of OA. Volatility distributions of …

Chemical models of atmospheric particles are vital in understanding the role of aerosol
particles in atmospheric chemistry, air pollution, human health, and climate change …
