Why Urban Meteorology Now?

  • Technological Advances

    • Remote sensing and other platforms

    • Computer models

  • Homeland Security

    • Atmospheric Transport and Diffusion (ATD) models

  • Health and Safety

    • Air quality

    • High impact weather

Technological Advances

NOAA is working toward an integrated observing system to take into account a myriad of observational data and optimize their use.

  • Satellite data

  • Climate Reference Network

  • UrbaNet – New York/Washington

  • Private sector ‘Weather Nets’

  • In situ observations

  • Buoys

Dust Storm Pushing Air Pollution


Air Pollution




Dust and Air Pollution Flowing Out of China Destined for the United States (April 2001)

Initial UrbaNet Met Site: DOC (Hoover) Building

Data Collected:

3-D Wind Vectors



Relative Humidity

Solar Radiation

Data are collected in one minute intervals and the summaries are transferred every 15 minutes.

UrbaNet - Washington, DC(NOAA coordinated effort with Army, DOE, DTRA)

The 12 Yellow squares are currently operating sites.

The additional 12 Green squares are planned sites as funding permits

UrbaNet displays a well-known feature -- standard airport data are not appropriate for downtown dispersion applications.

Homeland Security

Model of Lower Manhattan at NOAA’s Air Resources and EPA wind tunnel facility, at Research Triangle Park, N.C.

HYSPLIT-Hybrid Single Particle Lagrangian Integrated

Trajectory model

The red dots show trajectory end points at hourly intervals.

At small scales, UrbaNet data are now being assimilated.

  • The inclusion of UrbaNet data can have a significant impact.

  • Prediction based on

    12 km Eta alone.

  • Prediction based on

    12 km Eta but nudged towards UrbaNet data.

Homeland Security

Support a system to orderly evacuate cities during hazardous events.

Health and Safety

Air Quality Program

Scientific Advice for Decision-Makers

Regional Assessments discover key atmospheric processes that contribute to poor air quality

Houston: refinery emissions

New England: nocturnal chemistry

Air Quality Forecasting

Operational implementation for ozone initially, then particulate matter and others

New England

Ohio River Valley

Lake Michigan

Mid Atlantic

Central California

Southern California


1995, 1999

East Texas


Areas with the Most Serious* Air Quality Problems

Chemically and Meteorologically Diverse

*Designated by EPA as “serious”, “extreme”, or “severe” for ozone and/or PM

National Air Quality ForecastingPlanned Capabilities

  • Initial: 1-day forecast guidance for ozone

    • Develop and deploy in Northeast by 9 / 2004

    • Deploy nationwide within 5 years

  • Intermediate (5-7 years):

    • Develop and test capability to forecast particulate matter concentration

  • Longer range (within 10 years):

    • Extend air quality forecast range to 48-72 hours

    • Include broader range of significant pollutants

Health and Safety

Urban areas are especially vulnerable to high impact weather, because of the concentration of lives and property.

  • Hurricanes – destructive winds and storm surge

  • Severe thunderstorms and tornadoes - affect trees, power lines, and buildings

  • Heat waves – direct cause of more deaths than all other weather conditions combined

  • Winter weather – impacts on transportation and utility infrastructure

Heat Waves

High Impact Weather

U.S. Hazards Assessment


  • Need for an urban focus was magnified by 9/11 attacks, but longstanding issues regarding health and safety continue to demand attention

  • New observing systems and improved models point the way forward for research

  • Complexity of urban meteorology issues demands that NOAA partner with broader community to advance research and development
