Historically the Wasatch Front has exceeded the existing one-hour ozone standard, and is expected to have difficulty meeting the new 8-hour standard. To better understand and forecast these exceedance episodes the Utah Division of Air Quality (UDAQ) has elected to apply the Urban Airshed Model (UAM). The application of UAM in this area is difficult because of the Wasatch mountain range to the east of the urbanized area and the Great Salt Lake to the west. The UDAQ sponsored a field data measurement project during the summer of 1996 to support the UAM effort. Special intensive measurements of meteorology, precursor emissions, and chemistry, at ground level and aloft, were conducted on five days to develop a more complete understanding of ozone and its evolutionary process. Aircraft and ground-based mobile measurements of air quality and meteorology supplemented the existing networks to define the boundary conditions as well as document the chemical changes and transport within the airshed. On the study days ozone concentrations did not exceed the 1-hour standard but did exceed the 8-hour standard. The field effort has provided valuable data for characterizing the complex meteorology and boundary conditions in the airshed. This paper discusses the data analysis as it applies to the development of wind fields with the Diagnostic Wind Model (DWM)1 for use in the UAM.
