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 …

Light-absorbing carbonaceous aerosols (LACs), including black carbon and light-absorbing
organic carbon (brown carbon, BrC), have an important role in the Earth system via heating …

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 …

Multiple linkages connect air quality and climate change. Many air pollutant sources also
emit carbon dioxide (CO2), the dominant anthropogenic greenhouse gas (GHG). The two …

Major components of suspended particulate matter (PM) are inorganic ions, organic matter
(OM), elemental carbon (EC), geological minerals, salt, non-mineral elements, and water …

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 …

We describe a novel inlet that allows measurement of both gas and particle molecular
composition when coupled to mass spectrometric, chromatographic, or optical sensors: the …

The present paper reviews existing knowledge with regard to Organic Aerosol (OA) of
importance for global climate modelling and defines critical gaps needed to reduce the …

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 …

Secondary organic aerosol (SOA), particulate matter composed of compounds formed from
the atmospheric transformation of organic species, accounts for a substantial fraction of …
