Meteorological Factors in Dispersion Modelling of SO2 and NO2 in Baia Mare, Romania

Abstract

Atmospheric dispersion characterizes the evolution in time and space of an ensemble of pollutants (aerosols, gases, dust) emitted into the atmosphere. Atmospheric dispersion phenomenon is influenced by atmospheric conditions, soil parameters and emission values. The atmospheric dispersion model is the mathematical simulation of how air pollutants disperse. Such models are used to estimate the concentration of air pollutants emitted from industrial activity, domestic, rural and difuse sources. The paper presents the variety of atmospheric dispersion models on concentrations of SO2 and NO2 made according to the time variation of meteorological parameters (atmospheric pressure, relative humidity, rainfall, wind speed and solar radiation) specific to the Baia Mare urban area.
