Heterogeneous production of nitrous acid on soot in polluted air masses
- M. Ammann, M. Kalberer, U. Baltensperger
- Environmental ScienceNature
- 1 September 1998
Polluted air masses are characterized by high concentrations of oxidized nitrogen compounds which are involved in photochemical smog and ozone formation. The OH radical is a key species in these…

Influence of sublimation on stable isotope records recovered from high-altitude glaciers in the tropical Andes
- W. Stichler, U. Schotterer, B. Pouyaud
- Environmental Science, Geography
- 16 October 2001
Sublimation dominates the ablation process on cold, high-altitude glaciers in the tropical Andes. Transport of water vapor through the firn and exchange with ambient moisture alter the stable isotope…

A Gas Ion Source for Radiocarbon Measurements at 200 kV
The novel tabletop miniaturized radiocarbon dating system (MICADAS) at ETH Zurich features a hybrid Cs sputter negative ion source for the measurement of solid graphite and gaseous CO2 samples. The…
On-line Radiocarbon Measurements of Small Samples Using Elemental Analyzer and MICADAS Gas Ion Source
An on-line measurement system was installed at the MICADAS in Zurich, using an elemental analyzer (EA) as a combustion unit to enable direct radiocarbon measurement of samples containing carbon in…
Aerosol climatology at the high‐alpine site Jungfraujoch, Switzerland
- U. Baltensperger, H. Gäggeler, P. Seibert
- Environmental Science
- 27 August 1997
Continuous aerosol measurements have been performed at the high-alpine site Jungfraujoch (3450 m above sea level) since 1988 by means of an epiphaniometer. The instrument, which determines the Fuchs…
