Conclusions
A “One-Atmosphere” modeling approach has been taken to help assess the impact of control strategies on air quality in the Southern Appalachians. The modeling system, consisting of RAMS, EMS-95 and URM, simulates gaseous and condensed phase pollutants, and uses a sectional approach to provide size distributions of the aerosol. It is also used to simulate dry and wet deposition. In this paper, the model’s results were compared against a suite of observations for ozone and PM concentrations, as well as wet deposition, for four episodes.Two of those episodes were relatively wet, and two drier. While the results tended to be good for both sets of episodes,there was a tendency to overestimate ozone and underestimate aerosols during the wet episodes.
