The Interagency Workgroup on Air Quality Modeling (IWAQM) was formed to provide a focus for development of technically sound, regional air quality models for regulatory assessments of pollutant source impacts on Federal class I areas. The purpose of these meetings was to review respective regional modeling programs, to develop an organizational framework, and to formulate reasonable objectives and plans that could be presented to management for support and commitment. The report documents results from a series of sensitivity analyses of several meteorological models and puff dispersion moels suitable for application to air pollution dispersion involving long range transport. One of the primary objectives was to assess whether the introduction of the hourly, gridded 80-km mesosclae meteorological data with improved spatial and temporal resolution over typical observational networks would improve the quality of the characterization of the transport and dispersion. Based on the results obtained there was a noticeable improvement in the trajectory of the transport when mesoscale meteorological data were employed in comparison to results obtained using diagnostic winds developed using available wind observations. This report is the fourth document published by the IWAQM.
