Satellite-borne remote sensing of trace gases (SAT)

Welcome on the Satellite Group's homepage

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:


Reconstruction of energetic particle produced NOy for climate calculations


The figure shows the reconstructed stratospheric polar winter deposition of reactive nitrogen NOy (= HNO3 + NO2 + NO + 2*N2O5 + ClONO2 + HNO4) produced by energetic particle precipitation (EPP-NOy) higher up (i.e., in the mesosphere and lower thermosphere) in the Southern (red) and Northern (blue) hemisphere during 1850 - 2015, calculated with a model derived from MIPAS observations. Solar cycle (duration ~ 11 years) average depositions are indicated by the dashed lines. EPP-NOy contributes to ozone destruction and impacts climate, via the heating of the stratosphere by ozone and related circulation changes.
