The UV Satellite Data and Science Group (UVSat) is part of the Section "Physics and Chemistry of the Atmosphere" (Prof. John Burrows) within the Institute of Environmental Physics (IUP, Institut für UmweltPhysik). Group leader of UVSAT is Mark Weber.

Our research covers the following areas

  • satellite remote sensing
  • atmospheric chemistry and dynamics
  • ozone-climate interaction
  • solar physics

We are working mainly with the satellite instruments GOME (1995-2011), SCIAMACHY (2002-2012), GOME-2 (since 2006) and TROPOMI (since 2017).

 

Antarctic ozone hole in October as observed by GOME, SCIAMACHY, and GOME-2. The total ozone columns were retrieved with our scientific algorithm based upon the weighting function differential optical absorption technique (WFDOAS). In 2015 and 2018 the area of the Antarctic ozone hole was among the largest on reocrd. In 2019 the ozone hole was among the smallest. The last three years (2020-2022) the ozone holes were unusually large, possibly linked to the Australian wildfires (2020) and the volcanic eruptions from La Soufriere (2021) and Hunga Tonga – Hunga Ha’pai (2022) injecting large amounts of aerosols into the stratosphere.
