Abstract
The MesoSTEM model is used to analyse data obtained during the Mesoscale Acid Deposition Study. The Mesoscale Acid Deposition Study was designed to investigate acid deposition on the urban-suburban scale by sampling well defined frontal storms around the city of Philadelphia using a surface based network. The MesoSTEM model was developed to provide diagnostic analysis of these data. The mesoSTEM model is a combination of the Mesoscale Atmospheric Simulation System (MASS) predictive mesoscale dynamic meteorological model and the STEM-II model, a three-dimensional Eulerian acid deposition model. The MesoSTEM model is described in this paper and applied to the analysis of the 2 May 1985 storm. Elevated sulfate and nitrate deposition is predicted downwind of the major source areas and nitrate deposition exceeds that for sulfate. However, much of the NO
x
and SO
x
emitted on the mesoscale escapes the storm and becomes available for long-range transport and subsequent deposition.
