Joint Action Group for Joint Urban Test Beds

The Joint Action Group (JAG) meeting on October 4, 2007, reviewed progress on urban test beds, focusing on criteria selection, required infrastructure, and prioritization methodologies. Participants discussed urban air quality issues, lessons from the AMS 7th Symposium, and the integration of advanced modeling techniques. Notable topics included data assimilation challenges, urban infrastructure characterization, and geo-targeted alert systems for emergency warnings. Attendees emphasized the need to bridge gaps in current urban modeling approaches and identified critical deficiencies in test bed capabilities.

  1. Joint Action Group for Joint Urban Test Beds 4 Oct 2007 Cochairs: Dr. Walter Bach, Jr. and Mr. William Pendergrass Exec Secretary: Lt Col Mark Fitzgerald, USAF Telecon # 888-680-9581, pass code 535430# GoToMeeting https://www.gotomeeting.com/join/111054474, ID is 111-054-474

  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

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

  17. DC Network NOAA Silver Spring

  18. US Dept. of Commerce (Hoover Building)

  19. GEO-Targeted Alerting System Mr. Rich Jesuroga

  20. Geo-Targeted Alerting System

  21. 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.

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

  23. Timeline

  24. Action Item Update
