Research

The group investigates atmospheric transport processes and their role in determining the climate effect of high-altitude emissions.

In fundamental research, numerical transport models (Chemistry-Climate Models, CCMs; Chemistry-Transport Models, CTMs) are used to consistently quantify stratospheric exchange and residence times. Core methods include attribution approaches to diagnose individual processes and perturbation methodologies that isolate cause and effect relationships.

In applied research, the group develops surrogate and response models that efficiently approximate complex model chains. These tools enable rapid, physically interpretable assessments of the climate effect of aviation, space transport, and other high-altitude emissions.

The group works closely with the Modular Earth Submodel System (MESSy)
