10-Years Air Pollution Research In London 10-Years Air Pollution Research In London Sources of particles from a vehicle exhaust brake wear resuspension tyre wear road surface wear 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) Road Transport Projections: April 2009 Base Tim Murrells & Yvonne Li Air Pollution Research in London – Transport & Noise Group Meeting Imperial College 6 ACTUAL Advanced Climate Technology Urban Atmospheric Laboratory (5 years, started March 2009) “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 Measurement sites (REPARTEE I & II) Regent’s Park BT Tower REPARTEE campaign 2007 Regents Park DAPPLE roof site Lidar Site c. 1.6 km BT Tower Aim: Intensive observations of aerosols, trace gases and boundary layer dynamics to quantify variability in urban pollutants due to both chemical and meteorological processes.
