Atmospheric Tracers

Welcome to the homepage of the working group „Atmospheric Tracers“

The scientific focus of our working group is on atmospheric tracers. We use measurement data of trace gases to investigate a variety of atmospheric processes. Most experimental data are provided by our GC/MS (Gas Chromatography/Mass Spectrometry) instruments and analyses are completed by data of multiple atmospheric chemistry transport and chemistry climate models. The most important fields of research are:

  • Analysis of global chemistry transport and chemistry climate models, to study the interaction of transport, mixing and chemistry in the atmosphere. We also use these data to verify newly developed concepts and methods, which are then used to interpret our in-situ trace gas measurements. The models include, amongst others, the EMAC and the CLaMS model.

Tropospheric air masses enter the stratosphere via the tropical tropopause, from where they are distributed via different pathways in the stratosphere. Trace gas measurements can help in identifying different pathways and their relative importance.
