It has been shown that sunlit snow and ice plays an important role in processing
atmospheric species. Photochemical production of a variety of chemicals has recently been …

The discovery of the first chemically produced mass-independent isotope effect in 1983 by
Thiemens & Heidenreich opened a broad variety of applications, including physical …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Nitrate (NO3−) concentrations in public water supplies have risen above acceptable levels
in many areas of the world, largely as a result of overuse of fertilizers and contamination by …

The formation of inorganic nitrate is the main sink for nitrogen oxides (NO x= NO+ NO 2).
Due to the importance of NO x for the formation of tropospheric oxidants such as the …

The oxygen isotopic composition (Δ 17 O) of atmospheric nitrate is a function of the relative
abundance of atmospheric oxidants (O 3, RO x= OH+ HO 2+ RO 2) and the formation …

We use observations of the mass‐independent oxygen isotopic composition (Δ17O) of
sulfate in the marine boundary layer (MBL) to quantify the sulfate source from aqueous SO2 …

We use observations of the oxygen‐17 excess (Δ17O) of sulfate in the Arctic to quantify the
sulfate source from aqueous SO2 (S (IV)) oxidation by O2 catalyzed by transition metals …

Throughout the year 2001, aerosol samples were collected continuously for 10 to 15 days at
the French Antarctic Station Dumont d'Urville (DDU)(66° 40'S, l40° 0'E, 40 m above mean …

Abstract Nitrate (NO3−), which is mainly oxidized from NO2 by the OH radical (OH·) and O3
in the atmosphere, is a major component of inorganic aerosols. However, the contributions …
