Questions to Address In real urban settings What are individual exposure levels & what controls them? What determines relationships between emissions and exposure? How is personal exposure related to monitored air quality? How do pollutants move in & over a street network? How is material transferred to the ‘intermediate field’? How well can we predict these issues? How do we best go about managing air quality and exposure? What tools are needed to deal with this? Are these also suitable for incident management?

What We Will Do To cover scales of interest in space and time Conduct field experiments and monitoring. Carry out wind tunnel experiments. Undertake advanced computer modelling (CFD studies). Use these to provide full spatial & temporal description. Evaluate current operational models. Interpret what we learn - understand the science. Draw key lessons from the total activity. Develop new prediction methodologies & improve existing ones. Support spin-off activities.

Deliverables Science - through seminars, conferences, papers Data - accessed through internet or available on CD Methodologies - specifications and evaluations Best practice - guidelines (ERCOFTAC) Education & training - seminars & workshops Project workshops for rapid & focussed dissemination Web-site - for rapid dissemination Presentations - for advisory group members & third parties Reports & papers - formal final deliverables

Training - Skills Exchange To widen skills base Close collaboration with EPSRC CUPT project - Uni. of Leeds Maximise interaction between partners Exchanges between researchers Training seminars and workshops Regular progress reporting - seminars, news letters, www Timely transfer of outputs to user group Offer straightforward third party access Maximise the significance of the project to the whole community

Third Party Access Encourage & third party involvement (projects, PhDs, etc.) by: associated (field) experiments collaboration in the wind tunnel studies associated or independent modelling studies independent use of data and by early provision of data early knowledge transfer through workshop & seminars establishing full data base of project outputs through membership of the Project Advisory Group.
