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.

MIPAS provides global ozone distributions from the lower stratosphere to the lower thermosphere
The spectral measurements of MIPAS in the middle (MA) and upper atmosphere (UA) mode and the noctilucent cloud (NLC) mode provided observations of ozone that cover the lower stratosphere (20 km) up to the lower thermosphere (105 km), continuously from January 2007 to April 2012. The figure shows the time series of derived ozone mixing ratios for daytime (left) and nighttime (right) in the tropics (top) and the Northern polar regions (bottom). The white stripes are periods when there is no nighttime and daytime condition, respectively, over the pole. The retrieved ozone data provide all expected features like the strong diurnal variation above about 55 km, seasonal and semi-annual variations, the tertiary ozone maximum in polar regions during winter around 70 km, and a solar signature in phase with the solar cycle around 90 km during day in the tropics.
