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

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

5
Designs

• Build the test bed incrementally
• Cant cover all scales
• Cant 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

6
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 ( IOPs)

Communications

• With user communities joint production and
  feedback of new products
• With science communities RD needs being met?
  developments, testing
• With public Newspapers, Radio TV, Internet
• With education schools, libraries

10
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

11
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
