and atmosphere-biosphere interactions. The impact of climate change on these processes is also a major
feature of his research work. Has participated in several international projects, ACCENT Photocomp, TF
HTAP and Greencycles. Has also worked on contracts with the UK Defra, using various model experiments
to answer policy-relevant questions concerning possible emission changes and related air quality changes.
M. Shekar Reddy
Areas of interest include the emissions inventory development, and modelling of atmospheric transport of
aerosols and their climate impacts from regional to global scales. He has expertise in development
technology of based emissions inventories for the south Asian region and regional climate impacts. He is a
contributor to international aerosol intercomparison project.

Partner 16: University of Hamburg (UHam)
Expertise and experience of the organization
The UHam (appx. 40000 students) is Germany's 5 th 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).
