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

Status Update

Progress to date

New Direction

Leverage DCNet for momentum

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

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 DCNetOklahoma City

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).

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

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

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

Identify Test Bed Capabilities

Suggested capabilities Critical Deficiency: Vertical profile of winds/temp

GEO-Targeted Alerting System Mr. Rich Jesuroga

Geo-Targeted Alerting System

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.
