1. Current and future work: the ACTUAL and ClearfLo projects

2. 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)

3. ACTUAL Objectives: 1) Set up ACTUAL measurements: Platform 1: remote sensing * Doppler lidar * Sodar, with Stuart Bradley at Uni. Of Auckland * Comparison with scintillometer deployed by Sue Grimmond at King’s College London Platform 2: Westminster City Council roof (since Oct 2006) Platform 3: BT Tower Platform 4: Wind tunnel simulations (Uni. of Surrey), collaboration with A. Robins Deployment spring 2010 Data available throughout website by autumn 2010 Advanced Climate Technology Urban Atmospheric Laboratory z BT = 190 m Z ~ 2-3H Z = H Z ~ 9H

4. ACTUAL 2) Assess the validity and impact of urban climate simulation (partners: The Met Office, Peter Clark) Advanced Climate Technology Urban Atmospheric Laboratory

5. ACTUAL 3) Quanify the effect of building layout and design on urban climate (Partners: Arup, Jake Hacker, Andrew Allsop) Advanced Climate Technology Urban Atmospheric Laboratory

6. ACTUAL 4) Determine the effect of urban climate on energy supply and demand (with Tim Cockerill at Imperial College) Advanced Climate Technology Urban Atmospheric Laboratory

7. ClearfLo NERC funded consortium, £2.8million over 3 years, combined meteorological and chemical observations and modelling Start date January 2010 Regular Knowledge Exchange meetings, part hosted by APRIL Two Intensive Observation Periods (summer/winter pollution episodes, TBC)

8. ClearfLo Objectives are to: -Establish an infrastructure for air quality research -Measure a meteorological and chemical “climatology” of London -Determine meteorological and chemical processes governing concentrations -Focus on ozone, nitrogen dioxide and particulates -Evaluate air quality modelling (WRF-CMAQ)

9. Sites: central London; urban background (NK); rural (Chilbolton, Harwell, Detling) O3, CO, NOx, PM, SO2 existing; add AMS for particulate species on BT Tower. DOAS for NOx profiles through boundary layer Add eddy covariance (fluxes), scintillometer (path averaged heat fluxes), ceilometer (boundary layer depth) Sites at different heights (NK, MR – street; KCL – rooftop; BT – 190m) Medium term measurements (2 years) integrating study of met and chemical processes
