Hygroscopicity is one of the most important physicochemical properties of aerosol particles
and also plays indispensable roles in many other scientific and technical fields. A myriad of …

ABSTRACT Fine particulate matter (PM2. 5) is a well-established risk factor for public health.
To support both health risk assessment and epidemiological studies, data are needed on …

Natural aerosols in pristine regions form the baseline used to evaluate the impact of
anthropogenic aerosols on climate. Sea spray aerosol (SSA) is a major component of …

Low-cost sensors are useful tools for the collection of air quality data, augmenting the
existing regulatory monitoring networks and providing an unprecedented opportunity to …

Nocturnal dinitrogen pentoxide (N2O5) heterogeneous chemistry impacts regional air
quality and the distribution and lifetime of tropospheric oxidants. Formed from the oxidation …

Brown carbon (BrC) is an organic aerosol material that preferentially absorbs light of shorter
wavelengths. Global‐scale radiative impacts of BrC have been difficult to assess due to the …

The spatial distribution and properties of submicron organic aerosol (OA) are among the key
sources of uncertainty in our understanding of aerosol effects on climate. Uncertainties are …

Many cities in India experience severe deterioration of air quality in winter. Particulate matter
is a key atmospheric pollutant that impacts millions of people. In particular, the high mass …

Most intensive field studies investigating aerosols have been conducted in summer, and
thus, wintertime aerosol sources and chemistry are comparatively poorly understood. An …

The hygroscopicity of organic aerosol (OA) is important for investigation of its climatic and
environmental impacts. However, the hygroscopicity parameter κ OA remains poorly …
