Long-term goals of our research program are

  • to establish the distribution and properties of important trace gases, aerosols and clouds in the middle atmosphere,
  • to obtain a better understanding of the microphysical, radiative, and chemical interactions that determine their properties and variability, and
  • to understand underlying transport processes and the dynamical coupling between various parts of the atmosphere. 


Hygrosonde rocket launch Experimental efforts are at the core of our research programme. Remote sensing and in situ techniques are applied from satellites, sounding rockets, balloons and the ground. The development of retrieval algorithms complements this work. Laboratory studies aim at the development of improved measuring techniques. Related modeling efforts are essential to couple measurement data to our scientific objectives. Obviously, extensive international co-operation is of central importance for these projects.
