Partner 16 - UHam (Germany)
University of Hamburg  (UHam)

Expertise and experience of the organization
The UHam (appx.  40000 students) is Germany's 5th largest university. Structured in six faculties, the Faculty of Mathematics, Informatics and Natural Sciences is one of the largest and includes the Earth Sciences Department with the Meteorological Institute (MI) and Institute for Geography (IfGeogr). MI has several decades of experience in studies on weather and climate as well as on atmospheric dispersion and air pollution. MI has developed, validated and applied global to local scale numerical models, including the model system M-SYS that allows investigations of pollution transport and meteorology from the mesoscale down to the building-resolving micro-scale. The models are public and simplified versions of the developed models are used by consultants. MI is part of the Centre for Marine and Atmos. Sciences (ZMAW), where 300 researchers and PhD students jointly work in marine, climate and earth system research. Institute members collaborate in more than 100 national and international projects, and contribute to or coordinate several EU projects and COST actions. IGeogr covers all fields of geography including economic and social effects (e.g. regional accounts of environmental risks). Since the early nineties IGeogr is involved in elaborating indicators of sustainable urban development, planning strategies and scenarios for urban restructuring. More recently basic and applied research on urban growth strategies has been included within a frame of concepts of ecological modernization in urban governance. Currently IGeogr is involved in projects of recent trends of re-urbanisation and a new meaning of compact city strategies. The empirical work is based on GIS technologies. 

Role and contribution

MI will improve an existing parameterisation for sub-grid-scale urban effects (WP 2), implement it in the mesoscale meteorology and air quality model system M-SYS and validate it for the Rhine-Ruhr. M-SYS will be applied for the Paris case, which will also include an evaluation on different grids (WP5). The evaluated M-SYS will be implemented for Shanghai and studies on the Shanghai impact on the surrounding AQ will be performed (WP7). MI will co-lead WP7 and additionally contribute to WP7 by leading task 7.3, developing a joint evaluation method for the MEGAPOLI project and apply it to the different models and applications (WP 7). IGeopgr will develop scenarios of possible evolutions of megacities (Paris, London, Rhine-Ruhr, Shanghai, Mexico City, Shanghai) by qualitative descriptions of the possible development of settlement structure and infrastructure and advice in developing assumptions about the effect of these scenarios on transport, energy supply and emissions of air pollutants (WP 8).

Principal personnel involved
Dr. Heinke Schluenzen (Prof.; Ph.: +49-428385082; Fax: +49-428385452, e-mail: - is head of mesoscale/microscale modelling group at MI. She has long experience in model development, investigation of boundary layer and lower troposphere processes, 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: - 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
