Glaciochemical dating of an ice core from upper Grenzgletscher (4200 m a.s.l.)
- A. Eichler, M. Schwikowski, +5 authors M. Funk
- Geology
- 2000
One crucial condition for the interpretation of ice-core records is the establishment of an accurate time-scale. This task is especially difficult for glacier sites in a complex topography such as… Expand
A study of an outstanding Saharan dust event at the high-alpine site Jungfraujoch, Switzerland
- M. Schwikowski, P. Seibert, U. Baltensperger, H. Gäggeler
- Environmental Science
- 1 August 1995
Abstract From 20 until 23 March 1990 an outstanding Saharan dust episode was observed at the high-alpine site Jungfraujoch (3450 m a.s.l.), Switzerland. Detailed meteorological analyses including… Expand
Significance of semivolatile diesel exhaust organics for secondary HONO formation.
- L. Gutzwiller, F. Arens, U. Baltensperger, H. Gäggeler, M. Ammann
- Chemistry, Medicine
- Environmental science & technology
- 15 February 2002
The atmospheric origin of nitrous acid (HONO) is largely unknown despite its estimated importance as an OH source during daytime due to its rapid photolysis. Recently, primary HONO contained in… Expand
Influence of sublimation on stable isotope records recovered from high-altitude glaciers in the tropical Andes
- W. Stichler, U. Schotterer, +4 authors B. Pouyaud
- Geology
- 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… Expand
Historical record of carbonaceous particle concentrations from a European high‐alpine glacier (Colle Gnifetti, Switzerland)
- V. Lavanchy, H. Gäggeler, U. Schotterer, M. Schwikowski, U. Baltensperger
- Geology
- 20 September 1999
Historical records of the concentrations of black carbon (BC) and elemental carbon (EC), as well as of water insoluble organic carbon (OC) and total carbon (TC) covering the time period ∼1755–1975… Expand
Aerosol climatology at the high‐alpine site Jungfraujoch, Switzerland
- U. Baltensperger, H. Gäggeler, +4 authors P. Seibert
- Geology
- 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… Expand
Chemical characterization of element 112
- R. Eichler, N. V. Aksenov, +22 authors A. Yeremin
- Chemistry, Medicine
- Nature
- 3 May 2007
The heaviest elements to have been chemically characterized are seaborgium (element 106), bohrium (element 107) and hassium (element 108). All three behave according to their respective positions in… Expand
Heterogeneous reaction of NO2 on diesel soot particles.
- F. Arens, L. Gutzwiller, U. Baltensperger, H. Gäggeler, M. Ammann
- Chemistry, Medicine
- Environmental science & technology
- 20 April 2001
Soot particles were collected from a diesel engine using a procedure that realistically mimics exhaust gas conditions in tailpipes and during dilution at room temperature. After being sampled, the… Expand
Radiocarbon analysis in an Alpine ice core: record of anthropogenic and biogenic contributions to carbonaceous aerosols in the past (1650-1940)
Long-term concentration records of carbonaceous particles (CP) are of increasing interest in climate research due to their not yet completely understood effects on climate. Nevertheless, only poor… Expand
Effects of postdepositional processes on snow composition of a subtropical glacier (Cerro Tapado, Chilean Andes)
- P. Ginot, C. Kull, M. Schwikowski, U. Schotterer, H. Gäggeler
- Geology
- 16 December 2001
In order to study the effects of postdepositional processes on snow chemistry a surface snow experiment was performed on the Cerro Tapado summit glacier in northern Chile, a subtropical glacier site… Expand
