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).
A look on the Etihad EY474 turbulence encounter on 4 May 2016 from a Cb-global perspective
A turbulence encounter of a flight close to Sumatra caused atmospheric scientists from the DLR Institute of Atmospheric Physics and WxFUSION, a DLR spin-off company, to analyze this event with the new methodology Cb-global. This thunderstorm detection and nowcasting system is capable of detecting thunderstorms in near real time and to nowcast their future development. Cb-global is based on satellite data, in this case from Himawari-8 available in real time with a space/time resolution of 2 km (IR channels)/10 minutes. An analysis with Cb-global reveals that the severe turbulence encountered by the aircraft has most probably been caused by a rapidly developing convective cell.
Rare noctilucent cloud observed above southern Germany
Atmospheric scientists from the DLR Institute of Atmospheric Physics (IPA) succeeded in sounding of a so-called noctilucent cloud (NLC) using a LIDAR system developed at IPA. The measurement was recorded on 18/19 July at the Sulzberg in the Bavarian Forest, and shows a very thin, bright layer of ice crystals at 82 km altitude. Noctilucent clouds, also termed polar mesospheric clouds, are a common phenomenon above Earth's poles in summertime, when this region paradoxically proves to be the coldest place on Earth. Noctilucent clouds are rarely observed at mid-latitudes where observation conditions for LIDARs are optimal.
Planned satellite mission Merlin at “COP 21”
The Lidar department of the DLR Institute of Atmospheric Physics contributes substantially to the German-French satellite mission Merlin (‚Methane Remote Sensing LIDAR Mission‘). At the 2015 UN Climate Change Conference “COP 21” in Paris, Brigitte Zypries, German Parliamentary State Secretary at the Federal Ministry for Economic Affairs and Energy and Federal Government Coordinator of German Aerospace Policy, and Thierry Mandon, French Secretary of State for Higher Education and Research, underlined the role of spaceborne earth observation to document and investigate the climate change.
Flight tests for alternative fuels
Alternative fuels have the potential to support the environment and climate-friendly developments in air transport. At present, global air traffic contributes towards almost five percent of global warming. In addition to the greenhouse gas carbon dioxide, condensation trails and the resulting cirrus clouds lead to a significant climate impact. In a three-week series of flight tests lasting until 9 October 2015 within the ECLIF project (‘Emission and Climate Impact of Alternative Fuels‘), the DLR Institute of Atmospheric Physics in cooperation with the DLR Institute of Combustion Technology is investigating how to reduce the impact of air transport on the climate by using alternative fuels.
Forschungsflugzeug HALO: Auf der Langstrecke für Messungen im asiatischen Sommermonsun
Mit mehr als zwölf Messinstrumenten an Bord startete das Forschungsflugzeug HALO des DLR Ende Juli in Richtung Zypern. Von dort aus geht es dann für Messflüge in das Einflussgebiet des asiatischen Sommermonsuns über der Arabischen See, dem Indischen Ozean, dem Golf von Bengalen und dem östlichen Mittelmeer. Insgesamt fünf Wochen lang werden während der Mission OMO die Schadstoff-Emissionen ermittelt, die der Monsun vom Boden bis in große Höhen befördert und großräumig verteilt.
