  1. My Work at the German Aerospace Centerpl: Niemieckie Centrum Badań Lotniczych i Kosmicznychde: Deutsches Zentrum für Luft- und Raumfahrt (DLR)Arthur Schady

  2. Mission of DLR To open up new dimensions for exploring the earth and the universe, for protecting the environment and for promoting mobility, communication and security: • Research portfolio ranging from basic research to innovative applications and the products of tomorrow • Operating large-scale research facilities for DLR’s own projects and as a service provider for its clients and partners • Promoting the next generation of scientists

  3. European networking • Success in obtaining program funding from the European Union • Core formation in Europe for clearly defined strengthening of technical expertise and competitiveness • Expand the ability to determine the direction taken at European level

  4. International networking • Orienting bilateral cooperation • Multilateral cooperation in determining the framework and marketing of DLR products • Further developing instruments of international cooperation

  5. Aeronautics

  6. Space

  7. Transport

  8. Energy

  9. Transport • Resolving issues related to mobility, influencing and coping with the increase in transport • Energy saving, reducing pollutants that affect the climate and are harmful to the health and lowering noise emissions • Accident prevention, reducing the risks to people from accidents

  10. Visiting Scientist at DLR in Oberpfaffenhofen since 1.May 2006 My working fields: • NO2 related Data Analysis (http://www.pa.op.dlr.de/troccinox/) • Acoustic Modeling (http://www.pa.op.dlr.de/acoustics/)

  11. NO2 related Data Analysis (TROCCINOX) • Satellite Data (SCIAMACHY) • Model Data (TM4) • Emission Data (EDGAR, MESSy, GEIA,…) • Deposition Data • Lightning Data (LIS/OTD) Number of Data sets: 6+2+6+1+9 = 24 Number of different formats: 9 Number of produced images: 724 - 981
