Application of the CALMET meteorological model to UAM modeling in the northeast
- Earth Tech/Sigma Research Corp., Concord, MA (United States)
Many urban areas in the US have been designated by the US Environmental Agency (USEPA) as failing to meet the national air quality standard for ozone. The 1990 Clean Air Act Amendments (CAAA) describe a regulatory mechanism and a strict timetable for those regions presently in nonattainment to be brought into compliance. The USEPA has recommended that the Urban Airshed Model (UAM) be used as the photochemical grid model to demonstrate attainment strategies. In this study, the authors report on the application of a wind adjustment scheme that enhances the prediction of surface ozone concentrations by insuring a realistic transition from the surface wind field to flow above the mixed layer. The episode chosen is a high ozone day from July 1988. The effect of applying the scheme is shown in both the wind fields and the predicted ozone concentration fields.
