<p><span style="font-family:Arial,Helvetica,sans-serif">Four threshold air pollutants (SO₂, NO, NO₂, and O₃) in addition to meteorological parameters were monitored at the Campus of the Hashemite University (HU) for two years (1/1/2012 through 30/12/013). Correlations between air pollution and meteorological parameters were derived. The results showed that O₃ has a positive correlation with air temperature, wind speed and wind direction, but has a negative correlation with the relative humidity (RH). SO₂was found to have a negative correlation with the RH and wind speed, but positive correlation with air temperature. NO has negative correlation with air temperature, RH, and wind speed. And finally, NO₂ has a negative correlation with RH and wind speed, but it has positive correlation with air temperature. Justify the reasons in brief with recommendations to improve the air quality</span></p>
