Abstract:
Air quality modeling is an essential tool for most air pollution studies. The air quality models are the means whereby pollutant emissions can be related to atmospheric pollutant concentrations. The uncertainties in assessment of air quality are related to both the quality of measured values of pollutant concentrations in local network and the input data for the models. The better estimation of air quality requests to combine the results of measurements with the results obtained by modeling
The aim of our paper is to assess the air quality in Craiova and therefore the results of measurements were compared with the results of the two very used models in pollution studies: Climatologic and OML. The dispersion models are Gaussian-type models.
The OML (Operationelle Meteorologiske Luftkvalibets-modeller) improves the methods for the simulation of dispersion processes in terms of certain physical parameters, with importance to boundary layer turbulence.
Intercomparison study was applied for 3 sites in Craiova City, where the concentrations of pollutants were measured. The distribution in space and time of the TSP ( Total Suspended Particles) concentrations were studied.
The results show differences between measured and modeled values of TSP concentrations and consequently, for the assessment of air quality it is necessary to improve the methods of measurement of this type of pollutant and to be carefully with the input of meteorological data for models.
