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.

Shift of subtropical transport barriers explains observed hemispheric asymmetry of decadal trends of age of air
The figure shows the change of mean age of stratospheric air from the 2005-2008 to the 2009-2012 period (left row), for MIPAS (a) and the Langrangian transport model CLaMS driven by ERA-I reanalyses (c). The right row demonstrates how a latitudinal shift of the residual circulation (i.e. the latitudinal positions of the subtropical mixing barriers and the surf zones) affects the altitude-latitude distribution of mean age of air (the difference between the shifted and the original 2005-2008 distribution is shown). The shifts were determined from changes in the subtropical mixing barrier positions derived from N2O tracer pdfs.
