Head of the Institute
Institut für Physik der Atmosphäre
The Institute of Atmospheric Physics investigates the physics and chemistry of the global atmosphere from the Earth's surface up to the upper boundary of the middle atmosphere at about 120 km height. As an institute of the German Aerospace Center (DLR) we answer questions associated with atmospheric processes and with relevance to the research programmes "Aeronautics, Space, and Transportation" and "Energy" of the Helmholtz Association (HGF).
New insights on changes in the Ozone Layer
German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) researchers have been instrumental in the preparation of a report on the changes in the Ozone Layer for the World Meteorological Organization (WMO). The report was published online by the Geneva-based WMO in January. Recent estimates suggest that, by the middle of the 21st century, the thickness of Ozone Layer will be the same as in the early 1980s.
Helmholtz-University Young Investigators Group SeaKLIM presents its final report
Exhausts of industry, cars and aircraft are investigated since a long time because they significantly change the Earth’s atmosphere and the global climate. Only ship emissions remained unregarded for a long time. Since 2004 the impact of ship emissions on atmosphere and climate was investigated by the Helmholtz-University Young Investigators Group SeaKLIM, a cooperative project of the DLR Institute of Atmospheric Physics and the Institute of Environmental Physics of the University of Bremen. Now the final report is available: fine particles (aerosols) that are released into the atmosphere counteract the global warming, but contribute to air pollution.
MERLIN: French-German climate satellite to be launched in 2014
The Institute of Atmospheric Physics (IPA) is highly engaged with the development of the French-German satellite mission MERLIN (Methane Remote Sensing Lidar Mission). Over three years it has to be demonstrated that regional emission structures of the atmospheric trace gas methane and their temporal variations can be determined by active remote sensing techniques with good accuracy. As an effective greenhouse gas methane is an important component in the context of global climate change.
Flight tracks of the DLR Falcon volcanic ash missions
25 May 2010
Since April 19 altogether 17 flights were performed by the DLR Falcon research aircraft to survey and sample the emissions of the Eyjafjöll volcano on Iceland. The flight track data in ascii format are available for download.
Results of the first aircraft measurements in volcano ash clouds
10 May 2010
Between 19 April and 03 May 2010.nine flights of the DLR research aircraft Falcon were performed to measure the volcano ash load over Europe due to the Icelandic Eyjafjalla eruption. Comprehensive results of the successful measurements and supplementary observations by DLR and its partners have been summarized in a report which is now available for download. The results are used to derive measures for a better organization of air traffic during volcano eruptions. In future, concentration limits for save aviation will be defined. Then, forecast systems not only have to predict the presence of an ash cloud, but also have to quantify the mass concentrations. This is much more difficult, as modelling experts of other institutions confirm. The necessity for the operation of an emergency aircraft is clearly evident, not only in the case of volcanic ash, but also for other hazards. Heavy damage to the European economy could be avoided as the actual case has shown.
