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)

Air Pollution Research in London – Transport & Noise Group Meeting

Imperial College

6th July 2009

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)

Measurement sites(REPARTEE I & II)

Regent’s Park

BT Tower

REPARTEE campaign 2007

Regents Park

Lidar Site BT TowerDAPPLE 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

Site geometry

–Buildings different heights so expect asymmetries.

• Open arc may add to complexity.

• Site 2 further into canyon than site 1.
