Satellite-borne remote sensing of trace gases (SAT)
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.
Highlight of the month:
Water vapour and climate
Water vapour plays an ambiguous role in the climate system. On the one hand it is an important greenhouse gas in itself. On the other hand, its concentrations depend on temperature. Thus, the analysis of water vapour trends and their relation to temperature are an extremely relevant research field. To that end, Leonie Bernet and colleagues have analyzed atmospheric water vapour trends as measured by different measurement systems over Switzerland. A trend analysis tool developed at IMK was used for this purpose. The figure shows the temporal development of monthly mean water vapour content (top panel), anomalies (middle panel), and relative differences with respect to the TROWARA microwave radiometer in Berne (lower panel).
