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:


A spectroscopic issue was found to explain the differences between ozone profiles retrieved in MIPAS channels A and AB


The figure on the left shows mean ozone profiles of 59 orbits from 3 January, 1 April, 2 July and 2-3 October 2009, retrieved in MIPAS channels A (black) and AB (red) using the HITRAN-2008 spectroscopy. The blue profile results from retrievals in MIPAS channel AB after an increase in the air-broadened half widths of the ozone lines by a value of 0.005 cm-1 atm-1 at 296 K, and the green profile from retrieval after increase in the air-broadened half widths of the strongest ozone lines by 0.008 cm-1 atm-1 at 296 K. The figure on the right shows the absolute differences between retrievals in channels AB and A.
