Learning from Existing and Developing Test Beds OFCM Challenges of Urban Test Beds 10th GMU Conference on Atmospheric Transport and Dispersion Modeling Walter Bach Army Research Office 2 August 2006
Acknowledgments • Will Pendergrass – UrbaNet • Bruce Hicks – UrbaNet • Ken Crawford – Oklahoma City Urban Micronet • David Kingsmill – NOAA Hydro-Meteorological Test Bed • Jim Anderson – AWS WeatherBug • Maria Pirone – Private sector involvement • Many Others
Community • Community Attention • There are problems ! • Air Quality (ozone, emissions, health) • Public & private safety • Public & private transportation • Urban flooding • WMD • Severe weather – snow, ice, heat, cold, • Tailor the approach to the problems • Community Cooperation • Governmental Agencies • Emergency Services • Public Education • Each Community is different
Purpose / Objectives • Clear objectives for each Test Bed • KISS • Must serve multiple users • Long term • Attainable objectives • Community impact • Users impact • Science impact
Designs • Build the test bed incrementally • Can’t cover all scales • Can’t solve all the problems • Urban Test Beds are measurement driven • Forecast models have difficulty with urban scales • Motions are highly stochastic • Surface features (local & region) • Use in place processing where possible • Use robust wireless data transmission
Observations • QA/QC • Maintenance • Calibration • Precision of measurement • Multiple time & space scales • Highly variable wind statistics • Roof tops can work • Look above canopy – through BL • Provide for Campaigns ( IOP’s)

Communications • With user communities – joint production and feedback of new products • With science communities – R&D needs being met? developments, testing • With public – Newspapers, Radio –TV, Internet • With education – schools, libraries
Research • Measurements to study the whole boundary layer • Data assimilation in surface and sub-canopy layer. • Correlation lengths / times among network elements • Mixing heights • Scales really represented by measurements • How well does the network satisfy its objectives
Conclusions • The Urban Test Bed serves many masters in many different ways. • Community awareness and involvement are crucial to establishing the test bed. • It can always be improved • Beneficiaries must commit to support the development and maintenance of the test bed. • User and Science driven; Community benefit
