Aim of CLEAR

• Threefold aim
• To improve our scientific understanding of
  atmospheric processes, composition and pollution
  variabilities on local to regional scales
• To provide next generation tools for end users
  and stakeholders for managing air pollution and
  responding to its impact
• To help create a critical mass of expertise and
  ambition to address future research needs in the
  areas of air pollution, its impact and response
  strategies.

  London, Helsinki, Madrid)
• New emission factors,
• Analysis of traffic policies and air quality in
  EU cities
• SAPPHIRE PM2.5, PM10, inorganic and organics
  for Aporto, Birmingham, Athens, Helsinki,
  Copenhagen

Outputs of ATREUS

• Optimise the design of the buildings w.r.t.
  energy consumption
• Improve the feasibility on the use of the
  renewable energy for HVAC systems
• Reduce the heat island effect
• Evaluate the real energy budgets for cities
• Characterize the energy requirements of the city
  as a function of meteorological conditions
• Develop optimal methods for forecasting wind in
  complex topography and street geometry
• Develop and assess numerical modelling methods to
  evaluate heat exchanges between the buildings
  and the atmosphere
