| Gravity waves are important drivers of middle and upper atmospheric dynamics and trace gas transport, thus considerably influencing weather and climate at the surface. The PhD candidate will learn to apply global chemistry-climate models (e.g. EMAC) in order to analyze the influence of gravity waves on various temporal and spatial scales. The work will include handling in-situ and remote sensing observational data sets for comparisons and improving gravity wave parameterizations for a better understanding and representation of atmospheric processes.
