RELATIONSHIP BETWEEN AIR POLLUTANTS AND SOME METEOROLOGICAL PARAMETERS IN THREE CITIES OF ALBANIA

This paper aims to perform a statistical analysis in order to evaluate the level of relationships between air pollutants as ozone and nitrogen dioxide and meteorological parameters as air temperature, solar radiation and relative humidity in three cities of Albania. Air pollutants and meteorological parameters are measured continuously in Tirana city and on expedition basis in Elbasan and Fieri cities during year 2006. Three main episodes during this year are taken in consideration and the analysis is based on hourly values of air pollutants and meteorological parameters. Diurnal variations of air pollutants and meteorological parameters are investigated at three cities during these episodes. According to the results of the statistical analysis there was found a strong positive correlation between ozone and air temperature with correlation coefficient R up to 0.91 and between ozone and solar radiation with coefficient R up to 0.73. Negative correlations are found between ozone and minimum value of relative humidity with coefficient R up to -0.88 and between ozone and nitrogen dioxide with coefficient R up to -0.97. Based on the results of this analysis the relationship between air pollutants and meteorological parameters in three cities of Albania varies from moderate to strong levels.
