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 …

Organosulfates (OSs), also referred to as organic sulfate esters, are well-known and
ubiquitous constituents of atmospheric aerosol particles. Commonly, they are assumed to …

The acidity of aqueous atmospheric solutions is a key parameter driving both the partitioning
of semi-volatile acidic and basic trace gases and their aqueous-phase chemistry. In addition …

Isoprene has the highest atmospheric emissions of any nonmethane hydrocarbon, and
isoprene epoxydiols (IEPOX) are well-established oxidation products and the primary …

Isoprene-derived secondary organic aerosol (SOA) is mainly formed through acid-catalyzed
reactive uptake of isoprene-derived epoxydiols (IEPOX) onto sulfate aerosol particles. The …

Atmospheric ice nucleating particles (INPs) influence global climate by altering cloud
formation, lifetime, and precipitation efficiency. The role of secondary organic aerosol (SOA) …

Secondary organic aerosols (SOA) are crucial constitution of fine particulate matter (PM),
which are mainly derived from photochemical oxidation products of primary organic matter …

Physicochemical analysis of individual atmospheric aerosols at the most abundant sizes in
the atmosphere (< 1 μm) is analytically challenging, as hundreds to thousands of species …

Chemical mechanisms describe the atmospheric transformations of organic and inorganic
species and connect air emissions to secondary species such as ozone, fine particles, and …

Conspectus The pH of a solution is one of its most fundamental chemical properties,
impacting reaction pathways and kinetics across every area of chemistry. The atmosphere is …
