I hereby confirm that we would be interested in joining the EC 7FP proposal MEGAPOLI
(Megacities: Emissions, urban, regional and Global Atmospheric POLlution and climate effects, and
Integrated tools for assessment and mitigation) as a collaborating partner.
As stated in the project proposal, the MEGAPOLI's main goals will be to assess impacts of
megacities on local, regional, and global air quality, to quantify feedbacks between megacity air
quality, local and regional climate, and global climate change, and to develop improved integrated
tools for prediction of air pollution in megacities.
The Earth Systems Research Laboratory Assimilation and Modeling Branch (ESRL/AMB) is
specialized (among other areas of specialization) in integrated modelling tools. I have been the
working group leader ofthe Weather Research and Forecast/ Chemistry (WRF/Chem) working
group (http://www.wrf-mode1.org/WGl1).This modeling system is a community effort with a large
number of developers and users. We will be pleased to collaborate with the MEGAPOLI team.
Yours sincerely,
