We investigate the complex interaction of chemical and dynamical processes in the Earth's atmosphere on basis of distributions of trace gases, aerosols, clouds and temperature which we derive from spectral measurements of satellite remote sensing instruments. Our work field covers processing of satellite data and their validation, the research on physical and chemical processes in the atmosphere on the basis of the retrieved distributions of temperature, particles and trace gases, and the development and implementation of related satellite data analysis algorithms. The current focus of our work is the MIPAS-Envisat mission. The MIPAS satellite data derived by our group can be accessed here. Besides our work with MIPAS we are involved in the preparation of future space missions. On this website you find information about our publications, MIPAS-Envisat data, the annual MIPAS Data User Meeting, our radiative transfer model KOPRA, the team and our projects, as well as some pictures.

Rise and Fall of Solar Proton Generated NOx
The solar proton event in autumn 2003 generated huge amounts of NOx in the atmosphere. In cooperation with the Helmholtz Young Investigators Group "Solar variability, climate, and the role of the mesosphere/lower thermosphere" and the Instituto de Astrofísica de Andalucía, the production rates of NOx due to ionization and its lifetimes were studied. The figure shows time series of NOx between 50 and 90 degrees N at 62 km (top) and 45 km (bottom). more
