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 …

Because of the climate and air quality effects of organic aerosol, it is important to quantify the
influence of anthropogenic emissions on the aerosol burden, both globally and regionally …

Secondary organic aerosol (SOA) accounts for a significant fraction of ambient tropospheric
aerosol and a detailed knowledge of the formation, properties and transformation of SOA is …

Wildfires are increasing in frequency, raising concerns that smoke can permeate indoor
environments and expose people to chemical air contaminants. To study smoke …

We deployed a High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS)
and an Aerosol Chemical Speciation Monitor (ACSM) to characterize the chemical …

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 …

Light absorption of fine particle (PM 2.5) aqueous extracts between wavelengths of 200 and
800 nm were investigated from two data sets: 24-h Federal Reference Method (FRM) filter …

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 …

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 …

Relative contributions of water-and methanol-soluble compounds and their hydrophobic/
hydrophilic subfractions to the ROS (reactive oxygen species)-generating potential of …
