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 …

Biomass burning (BB) is a significant air pollution source, with global, regional and local
impacts on air quality, public health and climate. Worldwide an extensive range of studies …

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 …

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 …

Aerosol− cloud interactions account for the largest uncertainty in current estimates of
changes in radiative forcing according to the most recent IPCC report. 1 The term “aerosol …

Non-refractory submicron aerosol (NR-PM 1) species measured by an Aerodyne Aerosol
Chemical Speciation Monitor (ACSM) along with collocated gaseous species are used to …

Secondary organic aerosol (SOA) constitutes a large fraction of OA, yet remains a source of
significant uncertainties in climate models due to incomplete understanding of its formation …

Optical characteristics and molecular compositions of brown carbon (BrC) were investigated
during winter 2019 at a rural site of China with a focus on nitro-aromatic compounds (NACs) …

The particle number size distribution (PNSD) of airborne particles not only provides us with
information about sources and atmospheric processing of particles, but also plays an …

In recent years in a few Chinese megacities, fog events lasting one to a few days have been
frequently associated with high levels of aerosol loading characterized by high sulfate (as …
