Abstract. In this paper the results of the model intercomparison in the air
quality impact analysis of the Bitola Thermal Power Plant are presented.
The application of 3 atmospheric dispersion models, ADMS3, OML and
ISCST3 has been analysed. The ISCST3 model has been run with
meteorological input data generated by the MADAM Meteorological
Preprocessor. The main characteristics of the available data are the high
percentage of wind speeds below 1 m/s and the lack of mixing height
measurements. The performances of the models have been tested against
the ground level measurements of the daily mean SO concentrations
obtained at 4 locations around the point of release. The three model
results and the measurements at the presented locations for 365 days in
1998 arc compared.
