Atmospheric oxidation of sulfur dioxide (SO2) forms sulfate-containing aerosol particles that
impact air quality, climate, and human and ecosystem health. It is well-known that in-cloud …

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 …

Although the multiphase chemistry of SO2 in aerosol particles is of great importance to air
quality under polluted haze conditions, a fundamental understanding of the pertinent …

This assessment by the Environmental Effects Assessment Panel (EEAP) of the United
Nations Environment Programme (UNEP) provides the latest scientific update since our …

Ultraviolet (UV) radiation drives the net production of tropospheric ozone (O3) and a large
fraction of particulate matter (PM) including sulfate, nitrate, and secondary organic aerosols …

There is a large gap between the simulated and observed sulfate concentrations during
winter haze events in North China. Although multiphase sulfate formation mechanisms have …

How tiny aqueous aerosol droplets significantly accelerate the atmospheric multiphase
reaction remains an open question. Here, we show both experimental and theoretical …

Elevated particulate sulfate concentrations have been frequently observed in coastal areas
when air masses are influenced by continental emissions, especially combustion sources …

Sulfate aerosol contributes to particulate matter pollution and plays a key role in aerosol
radiative forcing, impacting human health and climate change. Atmospheric models tend to …

Conspectus The pH of a solution is one of its most fundamental chemical properties,
