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
ACTUAL Advanced Climate Technology Urban Atmospheric Laboratory Z ~ 9H zBT = 190 m Objectives: 1) Set up ACTUAL measurements: Platform 1: remote sensing * Doppler lidar * Sodar, with Stuart Bradley at Uni. Of Auckland * Comparison with scintillometerdeployed 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 Z ~ 2-3H Z = H
ACTUAL Advanced Climate Technology Urban Atmospheric Laboratory 2) Assess the validity and impact of urban climate simulation (partners: The Met Office, Peter Clark)
ACTUAL Advanced Climate Technology Urban Atmospheric Laboratory 3) Quanifythe effect of building layout and design on urban climate (Partners: Arup, Jake Hacker, Andrew Allsop)
ACTUAL Advanced Climate Technology Urban Atmospheric Laboratory 4) Determine the effect of urban climate on energy supply and demand (with Tim Cockerill at Imperial College)
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)
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)
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
ClearfLo • Principal Investigator: Prof. Stephen Belcher at Uni. of Reading • Collaborators: York, Leeds, Manchester, Salford, Hertfordshire, KCL, UEA, Birmingham, Reading, NCAS • Contact: s.e.belcher@reading.ac.ukfor more info
