How is the evolution of stratospheric ozone affected by climate change, and how strong is the feedback? (SHARP-OFC)

Description: Das Projekt "How is the evolution of stratospheric ozone affected by climate change, and how strong is the feedback? (SHARP-OFC)" wird vom Umweltbundesamt gefördert und von Universität Bremen, Institut für Umweltphysik durchgeführt. One major goal of this project is to analyse updated observational trace gas data together with stateof- the art models (CTMs and CCMs) in order to obtain a better understanding of the interaction between ozone and climate change and the underlying dynamical and chemical processes. The extended satellite, balloon and aircraft observations combined with improved model calculations (CTM and CCM) are used to further reduce the uncertainties in the bromine budget, in particular the contribution from VSLS (very short lived substances) and to further elucidate on the role of iodine in the stratosphere. Furthermore detailed studies on the long-term evolution (trends and variability) of observed stratospheric trace gases with foci on profiles of O3, NO2 and aerosols retrieved from SCIAMACHY are proposed. Future evolution of stratospheric ozone will be investigated using updated EMAC CCM model runs, some of them in combination with an interactive atmosphere-ocean feedback. In addition to issues on the climate feedback on future ozone, particular emphasis will be given to the increasing role of N2O and GHG emissions.
