Key Collaborators: Michael Brown, Department of Environment/Homeland Security Ron Cionco, U.S. Army Fei Chen, National Center for Atmospheric Research Maudood Khan, Georgia DNR Richard Fry, Defense Treat Reduction Agency Steven Burian, University of Utah

Project Abstract Written: October 2005

Project Timeframe: 2006 - 2008

Project Summary:

This project addresses the issue arising from the inadequacy of current meteorological models for urban AQ and dispersion applications and its resulting assessments. Proposed prototype system and layered database structure is designed to facilitate and accelerate and develop critical improvements needed for accurate meteorological predictions. Demonstration examples provided will serve to facilitate and encourage interest and subsequent general usage in air quality (e.g., CMAQ) and in advance dispersion modeling appropriate for contemporary and future urban air quality applications and exposure assessments.

Project will produce a prototype database for Houston and Atlanta and a portal delivery system which will contain primary urban building data and make accessible:

  1. urban canopy parameterization daughter products for meteorology models to drive urban air quality and dispersion modeling,
  2. ancillary data such as population activity data and
  3. examples of environmental (air quality, heat island mitigation studies) and exposure assessments applications.

The prototypes and portal template will allow expansion to the NGA's 133 monitored urban areas (that data will be made available through our Collaborators), it thus becomes resource for implementation of advanced meteorological modeling for urban applications on a national basis. Ancillary data and limited processing software are to be included as part of the Portal, as such, they serve to provide a capability for users to mimic the Prototype applications to the other cities.

Collaborations will provide critical inputs to Prototype including:

  1. accessibility to NGA data sets,
  2. refinements and/or extension of urban canopy daughter products for advanced urbanized MM5 and WRF modeling,
  3. population activity data model,
  4. provisions of software (freeware) to develop such daughter products from building database for other cities, and
  5. example to demonstrate decision maker usage towards performing advanced dispersion to multi-scale air quality modeling applications.
