Case Studies of Stratospheric Nitrogen, Chlorine and Iodine Photochemistry Based on Balloon Borne UV/visible and IR Absorption Spectroscopy
… play an important role in catalytic loss of stratospheric ozone. Balloon borne spectroscopic measurements of the vertical distribution of the most important nitrogen, chlorine and iodine containing species are used to estimate the quality of state-of-the-art instruments and retrieval …

Adjoint sensitivity analysis of the atmospheric impacts of combustion emissions
… and further develops an existing adjoint of a chemistry-transport model to perform three evaluations, where the high number of inputs (due to the nature of the problem or the associated uncertainty) prevented comprehensive assessment in the past. First, this thesis quantifies the pollution …

Timescales of processes controlling water vapour entry to the stratosphere
… vapour still influences surface warming and stratospheric chemistry due to its radiative and chemical properties. Previous studies have identified low temperatures (more accurately, low saturation mixing ratios) and large-scale transport through the tropical tropopause layer to be the key …

Ozone Chemistry in the Lower Stratosphere: Drivers, Trends, and Impacts
… results improving our understanding of both the chemistry and physics behind these processes and improvements to our ability to represent them in chemistry-climate models. This work is driven by the belief that improved understanding of the fundamentals of stratospheric chemical and physical …

Klimavariabilität der Tropo- und Stratosphäre in einem globalen gekoppelten Atmosphäre-Ozean-Modell mit vereinfachter stratosphärischer Chemie
In dieser Arbeit wurde die Variabilität der Atmosphäre in einem neuen gekoppelten Klimamodell (ECHO-GiSP) untersucht, welches eine vereinfachte Stratosphärenchemie (bis 80 km Höhe) enthält. Es wurden 2 Simulationen über 150 Jahre durchgeführt. In einer der Simulationen wurde die atmosphärische …
