Summary/Abstract: The air quality US EPA models-3 system consisting of SMOKE - emission model and pre-processor, MM5 – meteorological driver, and CMAQ – chemical-transport model, is used in many studies of the air quality in the Balkan Peninsula, and in particular Bulgaria. It runs in different model resolutions, depending on the domain, from European to city scale. The EMEP-MSC-W model is another chemical transport model, widely used in air quality modelling. Two of the processes involved in the concentration change of some pollutant are the dry and wet depositions. The air quality modelling capability depends on many factors, for example, meteorology and emissions. We study the differences in the simulation of the wet and dry depositions for nitrogen and sulphur compounds, between the CMAQ and the EMEP-MSC-W model for a period of 8 years.
