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
