Description
Summary:The model construction is described as well as the preparation of emission and meteorological data for the test period. For this period SO 2-concentration statistics were calculated by the model at the positions of four downtown measuring sites. The best agreement between observed and predicted concentrations was found if the stability over the city was always taken as independent of the surrounding rural area and corresponding to an unstable Pasquill-Turner class. Some residual scatter, probably due to measurement and source estimate inaccuracies remains, but the agreement is sufficiently good to justify further study.
