Many of the significant advances in our understanding of atmospheric particles can be
attributed to the application of mass spectrometry. Mass spectrometry provides high …

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 …

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 …

In recent years, Aerodyne aerosol mass spectrometers (AMS) have been used in many
locations around the world to study the size-resolved, nonrefractory chemical composition of …

We present a new instrument, the Aerosol Chemical Speciation Monitor (ACSM), which
routinely characterizes and monitors the mass and chemical composition of non-refractory …

Source apportionment using the bilinear model through a multilinear engine (ME-2) was
successfully applied to non-refractory organic aerosol (OA) mass spectra collected during …

Winter has the worst air pollution of the year in the megacity of Bei**g. Despite extensive
winter studies in recent years, our knowledge of the sources, formation mechanisms and …

Air pollution is a major environmental concern during all seasons in the megacity of Bei**g,
China. Here we present the results from a winter study that was conducted from 21 …

Atmospheric sulfate aerosols have important impacts on air quality, climate, and human and
