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.

Determination of biases and drifts from intercomparison of stratospheric water vapour satellite records - a contribution to the SPARC WAVAS-II activity
The figure shows the mean bias profiles of each data record against the average of all other data records (left: absolute biases; right: relative biases). The comparisons is based on inter-instrument coincidences during all seasons and at all latitudes. Each single-coincidence contribution to the biases is weighted by the total number of coincidences between the respective two data sets in order to weight dense and scarce samplers equally; within this weighting, all MIPAS data records are counted as one. For the sake of better visibility the results have been split among three rows. The separation is also reflected by the legend columns. In the legend the number of comparisons contributing to the summary for the individual data sets is also indicated.
