| Zusammenfassung |
| Very short-lived halocarbons are significant sources of reactive halogen in
the marine boundary layer, and likely in the upper troposphere and lower
stratosphere. Quantifying ambient concentrations in the surface ocean and
atmosphere is essential for understanding the atmospheric impact of these
trace gas fluxes. Despite the body of literature increasing substantially
over recent years, calibration issues complicate the comparison of results
and limit the utility of building larger-scale databases that would enable
further development of the science (e.g. sea-air flux quantification, model
validation, etc.). With this in mind, thirty-one scientists from both
atmospheric and oceanic halocarbon communities in eight nations gathered in
London in February 2008 to discuss the scientific issues and plan an
international effort toward developing common calibration scales (http://tinyurl.com/c9cg58).
Here, we discuss the outputs from this
meeting, suggest the compounds that should be targeted initially, identify
opportunities for beginning calibration and comparison efforts, and make
recommendations for ways to improve the comparability of previous and future
measurements. |
