The nitrate radical, NO3, is photochemically unstable but is one of the most chemically
important species in the nocturnal atmosphere. It is accompanied by the presence of …

Aerosol− cloud interactions account for the largest uncertainty in current estimates of
changes in radiative forcing according to the most recent IPCC report. 1 The term “aerosol …

Airborne particles affect human health and significantly influence visibility and climate. A
major fraction of these particles result from the reactions of gaseous precursors to generate …

Sulfur is an extremely motile and vital element in the Earth's biogeochemical environment,

Measurements of submicron aerosol chemical composition were made over the central
Arctic Ocean from 5 August to 8 September 2008 as a part of the Arctic Summer Cloud …

Sulfuric acid (H2SO4), formed from oxidation of sulfur dioxide (SO2) emitted during fossil
fuel combustion, is a major precursor of new airborne particles, which have well …

The atmospheric oxidation of dimethyl sulfide (DMS) represents a large natural source of
sulfate particles and thus is a major contributor to the global radiative effect of aerosols; …

Previous studies of the global sulfur cycle have focused almost exclusively on oxidized
species and just a few sulfides. This focus is expanded here to include a wider range of …

Daily PM10 aerosol samples were collected at the Gruvebadet observatory, Ny-Ålesund
