1. 10-Years Air Pollution Research In London

4. Sources of particles from a vehicle Emissions dependent upon vehicle speed (resuspension, tyre and road surface wear) engine revs and load (exhaust) driving mode (exhaust, brake, tyre, road surface) materials (brakes, tyres, road surface) fuel and lubricant (exhaust) vehicle weight and aerodynamics (resuspension) road surface silt loading (resuspension) exhaust resuspension tyre wear road surface wear brake wear

6. 6 Road Transport Projections: April 2009 Base Tim Murrells & Yvonne Li Air Pollution Research in London – Transport & Noise Group Meeting Imperial College 6th July 2009

7. ACTUAL “Buildings don’t just withstand climate, they change it” Aim: to challenge urban engineering practice by incorporating urban climate knowledge Funded by EPSRC under the Challenging Engineering programme Advanced Climate Technology Urban Atmospheric Laboratory (5 years, started March 2009)

8. Measurement sites (REPARTEE I & II) Regent’s Park BT Tower

9. REPARTEE campaign 2007 Regents Park Lidar Site BT Tower DAPPLE roof site Aim: Intensive observations of aerosols, trace gases and boundary layer dynamics to quantify variability in urban pollutants due to both chemical and meteorological processes. Special Issue in Atmospheric Chemistry and Physics! Collaborators: Birmingham, York, Manchester, Salford (FGAM), Reading, CEH, Lancaster, Leicester, Cambridge, Environment Agency, Bristol c. 1.6 km

10. REGENTS PARK FROM THE TOWER

11. THE REGENTS PARK AND TOWER ENVIRONMENTAL EXPERIMENT REPARTEE 2006 & 2007 Roy M. Harrison University of Birmingham

12. The use of the BT Tower in Environmental Research in London APRIL meeting, 26 th Jan 2010

13. Site geometry –Buildings different heights so expect asymmetries. Open arc may add to complexity. Site 2 further into canyon than site 1. With Permission of Microsoft Virtual Earth 1 2 3
