1972-1978  Studies of physics at the Technical University of Munich, diploma work on radiation-induced lattice defects in molybdenum, characterized by 181Ta Mößbauer-effect measurements (Prof. W. Gläser)

1979-1982  Doctoral studies at the Max-Planck Institute for Quantum Optics, title of thesis: “Laser-spectroscopic Studies of Iodine Monofluoride, formed in the Reactions of Fluorine Atoms with Iodine Halides” (Prof. H. Walther)

January 1983:  Graduation at the University of Munich (Ludwig-Maximilians-Universität)

1982-1986  Scientist at the Max-Planck Institute for Quantum Optics, starting in 1983: develop­ment of a state-selected beam of nitrogen ions generated by resonance-enhanced multi-photon ionization (Prof. K. L. Kompa)

1986-1987  Postdoctoral Fellow at the Lawrence Berkeley Laboratory and the University of California in Berkeley (Prof. Y. T. Lee), highlights:

§      development of the spectrally brightest tunable extreme-ultraviolet (XUV) radiation source to that date (bandwidth in the 90-120 nm range roughly 155 MHz), based on sum-frequency mixing with a near-transform-limited powerful dye laser system (130 mJ, 78 MHz bandwidth), in co-operation with Dr. A. Kung

§      Design and construction of a large molecular-beam photo-ionization experiment

§      High-resolution photo-ionization spectroscopy of H2, N2 (substantial improve­ment of the value of the N2 ionization energy), and Kr (XUV frequency deter­mination at an accuracy level of 6´10–9, detailed hyperfine and lifetime studies for five states)

§      Development of a liquid-nitrogen-cooled pulsed source of hydrogen molecules; photo-ionization studies of H2 and (H2)2 with tunable XUV light at 74 and 80 nm

§      1986: Nobel Price in Chemistry for Prof. Y. T. Lee

1988-1989  Scientist at the the Max-Planck Institute for Extraterrestric Physics; DFG-funded project on the investigation of ion-molecule reactions under interstellar conditions

1989  Second visit to Berkeley, attempt of a high-accuracy measurement (error < 15 MHz) of the ionization energy of H2 with two transform-limited pulsed dye lasers

Since 1990 Senior scientist at the Fraunhofer Institute for Atmospheric Environmental Research (IFU) (since 2002: Forschungszentrum Karlsruhe (now: KIT), IMK-IFU); field: development and application of laser remote sensing methods; highlights:


System Development:

Development of six wide-range mobile and stationary lidar systems for vertically resolved measurements of tropospheric trace constituents (ozone, water vapour and aerosol); the methods applied comprise the differential-absorption lidar (DIAL) method, the high-spectral-resolution technique and stimulated Raman shifting for generating 1.56-mm radiation. For achieving an operating range of the water-vapour DIAL up to 12 km a 250 mJ/20-Hz single-mode Ti:sapphire laser system was developed. Since 2009, a 350-W Raman lidar system for the measurement of stratospheric water vapour and temperature is under construction at the Schneefernerhaus laboratory (2675 m a.s.l.), alongside the high-power H2O DIAL. Currently, an improved Littman-type optical parametric oscillator is developed in co-operation with Radiant Dyes.


·      Validation studies for lidar backscatter experiments and contributions to several aerosol field campaigns for characterizing the impact of Alpine and marine aerosol on visibility conditions.

·      Investigation of the impact of atmospheric transport on the vertical distribution of atmospheric trace constituents, with emphasis on the Alpine wind system, stratosphere-to-troposphere transport and long-range (intercontinental) transport of polluted air masses, fire plumes and (North African and Asian) dust.

·      1996: first detection of pronounced North American ozone plumes over Europe; the first publication on this topic [A. Stohl, T. Trickl, Journal of Geophysical Research 104 (1999), 30445] defines a “Fast Moving Research Front” in Geosciences (Thomson ISI, July 2005)

·      Principal investigator in numerous national and international research projects, the most important ones being the EUROTRAC subprojects TESLAS, TOR and TOR 2, the EU projects VOTALP, VOTALP II, STACCATO, EARLINET, and the project ATMOFAST funded within the programme “Atmosphärenforschung 2000” of the German Federal Ministry of Education and Research; work-package co-ordinator in two EU projects

·      Co-ordinator of the project ATMOFAST (Atmospheric Long-range Transport and its Impact on the Trace-gas Distribution in the Free Troposphere over Central Europe, research programme “Atmosphärenforschung 2000” of the German Federal Ministry of Eduction and Research )

·      Since 2000: Principal investigator for the lidar activities at Garmisch-Partenkirchen within the Network for the Detection of Atmospheric Composition Change (NDACC, formerly NDSC) focussing on the long-term vertical sounding series of the (mostly volcanic) stratospheric aerosol started in 1976. In recent years the impact of forest fires on the stratospheric background has been investigated in selected case studies.
