Organic aerosol (OA) particles affect climate forcing and human health, but their sources and
evolution remain poorly characterized. We present a unifying model framework describing …

A simple formula to calculate the settling velocity of natural sediment particles for grain sizes
between 0.063 and 1 mm is presented. The formula has been derived from the previous …

BACKGROUND Exposure to droplets produced in the coughs and sneezes of infected
individuals or contact with droplet-contaminated surfaces (fomites) have been widely perceived …

During the rapid rise in COVID-19 illnesses and deaths globally, and notwithstanding
recommended precautions, questions are voiced about routes of transmission for this pandemic …

Organic aerosol (OA) data acquired by the Aerosol Mass Spectrometer (AMS) in 37 field
campaigns were deconvolved into hydrocarbon‐like OA (HOA) and several types of oxygenated …

The development of a new high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS)
is reported. The high-resolution capabilities of this instrument allow the direct …

A recently developed method to rapidly quantify the elemental composition of bulk organic
aerosols (OA) using a high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) …

Different on-line submicron particle sizing techniques report different “equivalent diameters.”
For example, differential mobility analyzers (DMAs) report electrical mobility diameter (d m ), …

The atmospheric chemistry of volatile organic compounds (VOCs) in urban areas results in
the formation of ‘photochemical smog’, including secondary organic aerosol (SOA). State‐of‐…
