2. Agenda

3. Welcome and Administrative Remarks • Welcome! • Administrative remarks • This meeting is being recorded • GoToMeeting • Approve ROA from last meeting

4. JAG/JUTB Overview • Formed in November 2005 • Charged with: • Developing criteria for test bed selection; • Defining the common required infrastructure for a multifunctional test bed; and • Defining a prioritization methodology for candidate uses of a test bed • Deliverable: Operational Concept Document

5. Status Update • Progress to date

6. New Direction Leverage DCNet for momentum

7. Lessons from San Diego –AMS 7th Symposium on Urban Environments

8. Strong International Interests • About ½ participants from out of US • Primary interest in urban air quality • From traffic and industrial emissions • Ozone, PM-10, PM-2.5 • Meeting European NOx standards ?? • Little interest in CBRN T&D • Urban Studies in • Shanghai London Marseilles • Tokyo Basel Houston • New York DCNet Oklahoma City

9. Focusing Models to Bridge Gap • Merging WRF, MM5, COAMPS mesoscale with CFD microscale. • Importance of Sea Surface temperatures for sea-breeze forecasts • Concerns about lateral and lower boundary conditions for hi-resolution models • Importance of BL height estimate & accuracy (mostly daytime).

10. Skimming Flow • Recommended for scaling of urban sub-canopy flows based on wind tunnel and in-situ measurements • Controversy on “roof-top” measurements • Oke – not reliable. Must get above building influences • Pendergrass – not always possible. Learn to use what we can get

11. Data Assimilation • Very little discussion of techniques beyond extrapolation • NCAR data assimilation models using mesoscale model forecasts, Doppler radar (NEXRAD and TDWR) and Doppler lidar find surface data of little value. • Not surprising • Asked for reports to explore verification and assumptions

12. Other Topics • JUTB • Provided 12 min presentation and supplemental discussion • Instrumentation • Doppler lidar wind profiler on building top to ~ 250 m • Scintillometers, large & small aperture, for integrated cross winds. • NUDAPT • Proceeding with characterization of urban infrastructure, land use, building properties, emissions, • USERS • Little discussion mostly AQ • U. Utah – Sustainable real estate development in SLC for 250 to 500 K new residence in 20 years

13. Identify Test Bed Capabilities • Suggested capabilities • Critical Deficiency: Vertical profile of winds/temp

14. Break 10 Min

15. DCNet Capabilities • Mr. Will Pendergrass

17. Current UrbaNet Sites • Potential Additional Military Sites • Planned Additional Sites 2 km

19. DC Network NOAA Silver Spring

20. US Dept. of Commerce (Hoover Building)

22. GEO-Targeted Alerting System Mr. Rich Jesuroga

23. Geo-Targeted Alerting System

24. GTAS Pilot Project • Geo-Targeting concept derived from exploratory reverse-911 work for weather warnings • Concept: Life-Threat warnings issued to public via reverse 911 call-outs • Conduct timing studies of life-threat targeted warnings with reverse 911 call-out technology (reverse-911 can target warnings to within 12 meter resolution) • DHS asked GSD to develop public warning concepts for potential toxic release in the NCR based on reverse-911 work.

28. JAG Member Participation • JAG members ID holes in DCNet capabilities • Identify Non-Federal JUTB Users • Questionnaire
