including chemistry, tracer and pollen transport as well as pollen and aerosol formation from the building
and forest resolving scale towards the European scale. She coordinates the development of the M-SYS
community model system, initiated model evaluation efforts, participated in several EU projects (e.g.
ANICE, SATURN) and is involved in the model evaluation tasks of current COST actions for mesoscale
(COST728, vice chair) and microscale (COST732) atmospheric modelling.
Dr. Juergen Ossenbruegge (Prof.; Ph.: +49-428384909; Fax: +4928384967, e-mail:
ossenbruegge@geowiss.uni-hamburg.de) - is head of the Department of Geography and leading a working
group on economic and social restructuring of urban areas. He has long experience in theoretical and
empirical research about spatial change and its environmental impact which includes pioneering research on
issues of sustainable development, innovation and regional development as well as quantitative and
qualitative concepts in order to evaluate risk perception and the effects of environmental policies for spatial
development. This work has resulted in various academic projects and policy advices for regional bodies in
the research areas which are related to sustainable urban development

Expertise and experience of the organization
The Department of Physical Sciences at the UHel has over 25 years tradition in atmospheric research. 60
scientists and doctoral students are currently engaged in this area. The main research subjects are aerosol
dynamics (nucleation, condensation, coagulation, deposition), formation and growth of atmospheric aerosol
particles and cloud droplets, atmospheric chemistry, urban aerosols, forest-atmosphere interactions (fluxes,
photosynthesis, water transport), aerosol-cloud-climate interactions, atmospheric boundary-layer theory,
modelling and parameterization. The basic theoretical resources consist of detailed computer codes
describing basic phenomena such as multi-component nucleation and condensation, photosynthesis, and of
extensive model for aerosol dynamics, atmospheric chemistry and cloud microphysics. The basic
experimental resources consist of three field stations (SMEAR : I, II, Urban) and a state-of-art aerosol
laboratory. In the field stations e.g. aerosol dynamics, atmospheric chemistry, micrometeorology, gas
exchange between forest and atmosphere, soil chemistry and forest growth are measured continuously.
Role and contribution
UHel is responsible for the aerosol science aspects including aerosol-climate interaction, ground based
observations and remote sensing, and for development of improved parameterization of the turbulent and
mean structures of UABLs for use in climate and air quality models.
