Halogens and their role in polar boundary-layer ozone depletion
- W. R. Simpson, R. Glasow, +22 authors E. Wolff
- Chemistry
- 22 August 2007
During springtime in the polar regions, unique photochemistry converts inert halide salt ions (e.g. Br − ) into reactive halogen species (e.g. Br atoms and BrO) that deplete ozone in the boundary… Expand
Ozone destruction and photochemical reactions at polar sunrise in the lower Arctic atmosphere
- L. Barrie, J. Bottenheim, R. C. Schnell, P. Crutzen, R. Rasmussen
- Environmental Science
- Nature
- 14 July 1988
There is increasing evidence that at polar sunrise sunlight-induced changes in the composition of the lower Arctic atmosphere (0–2 km) are taking place that are important regarding the tropospheric… Expand
An overview of snow photochemistry: evidence, mechanisms and impacts
- A. Grannas, A. Jones, +32 authors Tong Zhu
- Chemistry
- 22 August 2007
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 reported to occur in… Expand
Biogenic Hydrocarbons in the Atmospheric Boundary Layer: A Review
- J. Fuentes, M. Lerdau, +9 authors W. Stockwell
- Environmental Science
- 1 July 2000
Nonmethane hydrocarbons are ubiquitous trace atmospheric constituents yet they control the oxidation capacity of the atmosphere. Both anthropogenic and biogenic processes contribute to the release of… Expand
Snowpack photochemical production of HONO: A major source of OH in the Arctic boundary layer in springtime
- X. Zhou, H. J. Beine, +4 authors J. Bottenheim
- 1 November 2001
Both snow manipulation experiments and ambient measurements during the Polar Sunrise Experiment 2000 at Alert (Alert2000) indicate intensive photochemical production of nitrous acid (HONO) in the… Expand
Ozone Destruction and Photochemical Reactions at Polar Sunrise in the Lower Arctic Atmosphere
- L. A. Barrie, J. Bottenheim, R. Schnell, P. Crutzen, R. A. Rasmussen
- Chemistry
- 22 November 1988
A computer model study of multiphase chemistry in the Arctic boundary layer during polar sunrise
- Brian A. Michalowski, J. Francisco, S. Li, L. A. Barrie, J. Bottenheim, P. Shepson
- Chemistry
- 27 June 2000
A multiphase chemical box model of Arctic halogen chemistry has been developed using a PC-based modeling program developed by Environment Canada called the Chemical Reactions Modeling System… Expand
Measurements of C2‐C6 hydrocarbons during the Polar Sunrise1992 Experiment: Evidence for Cl atom and Br atom chemistry
- B. Jobson, H. Niki, Y. Yokouchi, J. Bottenheim, F. Hopper, R. Leaitch
- Chemistry
- 20 December 1994
The authors report the results of grab samples made in the Arctic winter atmosphere, which were analyzed for the presence of nonmethane hydrocarbons (C{sub 2} - C{sub 6}). The normal removal… Expand
Tracing the Origin and Fate of NOx in the Arctic Atmosphere Using Stable Isotopes in Nitrate
- S. Morin, J. Savarino, +4 authors J. M. F. Martins
- Chemistry, Medicine
- Science
- 31 October 2008
Atmospheric nitrogen oxides (NOx =NO+ NO2) play a pivotal role in the cycling of reactive nitrogen (ultimately deposited as nitrate) and the oxidative capacity of the atmosphere. Combined… Expand
A synthesis of atmospheric mercury depletion event chemistry in the atmosphere and snow
- A. Steffen, T. Douglas, +18 authors C. Temme
- Chemistry
- 12 March 2008
It was discovered in 1995 that, during the spring time, unexpectedly low concentrations of gaseous elemental mercury (GEM) occurred in the Arctic air. This was surprising for a pollutant known to… Expand
