The 2005 Union Service Award is awarded to Ulrich Pöschl for his pioneering and outstanding services with regard to the initiation and handling of the first journal of the Union to include interactive public discussions: Atmospheric Chemistry and Physics.
Ulrich Pöschl is heading a research group at the Max Planck Institute for Chemistry, Biogeochemistry Department (M. O. Andreae) in Mainz, Germany. He has studied chemistry at the Technical University of Graz, Austria, and he has worked as a postdoctoral fellow, research scientist, group leader, and university lecturer at the Massachusetts Institute of Technology, Department of Chemistry and Department of Earth, Atmospheric, and Planetary Sciences (M. J. Molina); at the Max Planck Institute for Chemistry, Atmospheric Chemistry Department (P. J. Crutzen); and at the Technical University of Munich, Institute of Hydrochemistry (R. Niessner). His current research and teaching activities are focused on the properties and interactions of aerosols and their effects on atmospheric chemistry and physics, climate, and public health (field measurements, laboratory experiments, and modelling of aerosol particle composition, structure, reactivity, and water interactions). As the initiator and chief executive editor of the interactive open access journal “Atmospheric Chemistry and Physics” he has started and established an innovative and successful initiative for improved scientific communication and quality assurance in collaboration with a globally distributed network of co-editors. Moreover, he serves as the president of the Atmospheric Sciences Division of the European Geosciences Union (EGU).
