  1. COST 715 Meteorology Applied to Urban Air Pollution Problems September 98-September 2003 • Problem • Issues covered • Successes • Conclusions

  2. Traditional approach to ABL non-dimensional profiles

  3. i ii iii wE Dynamics Thermodynamics In-street pollution

  4. unstable neutral stable stability sky conditions day night temperatureprofile height boundarylayerheight temperature turbulenceintensity radiationbalance Figure 3 Qualitative presentation of atmospheric turbulence intensity, temperature profile, and the radiation balance during unstable, neutral and stable atmosphere

  5. Parameters uC wind in urban canopy LC canopy length scale wE exchange velocity uref reference wind href blending height urural->uurban transfer function hurban height of urban boundary layer z0 roughness length based on geometry

  6. Relationship between incremental NOx and incremental NO2

  7. Relationship between incremental NOx concentrations in road side air and incremental NO2 concentration

  8. BUBBLE experiment Basel

  9. Recommendations on deriving meteorological parameters for application to urban air pollution estimates • Mixing height for urban background concentrations, atmospheric stability for dispersion • Street and urban background wind, for dispersion within above streets • Urban episodes, availability of tools, potential developments, uncertainty • Inventory of urban meteorological sites, use of data, recommendations for siting, local meteorological data and corrections, choice site location.
