Comparison of objective air-mass types and the Peczely weather types and their ability to classify levels of air pollutants in Szeged, Hungary
This paper compares the efficiency of a system of objective air-mass types and the Peczely's weather types in classifying pollution levels over the Carpathian Basin for the winter and summer months. Based on the ECMWF data set, daily sea-level pressure fields analysed at 00 UTC were related to the levels of air pollutants for both the objective air-mass types and the Peczely-types in Szeged. The ...

Air quality monitoring: establishing criteria for station classification
According to the Council Decision 97/101/EC on Exchange of Information, stations should be classified in relation to the type of area where they are located and according to the type of dominant emission sources influencing the air pollutant concentrations at the station. A detailed methodology was developed for the validation of the classification of Portuguese air quality monitoring stations, ...

Assessing the local scale annual air quality impact of industrial source from characteristic days
An approach of assessing the annual air quality impact of industrial sources from results of simulations performed for characteristic days, representative for different local scale dispersion conditions, is being studied. The methodology for selecting the characteristic days is presented. For classifications with different number of similar day clusters the air–quality directive limit and target ...
