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:

 

MIPAS age of air data were used to assess the ability of recent reanalyses to represent dynamics and transport in the stratosphere within the SPARC S-RIP project


The figures show the latitude-altitude cross-sections of trends of mean age of stratospheric air as derived from MIPAS SF6 observations for 2002-2012 (top left, Figure 5.24 of the report, adapted after Haenel et al., 2015) to similar age of air trend distributions from the BASCOE model driven by three different reanalyses (from Fig. 5.39 of the report, adapted after Chabrillat et al., 2018) for 2002 to 2015. Hatched and crossed areas, respectively, indicate data not being significantly different from zero (i.e. having an uncertainty of 100% or more). Please note the different color scales.  The SPARC Reanalysis Intercomparison Project (S-RIP) Final Report is available here.
