Peaks Over Threshold Method Application on Airborne Particulate Matter (PM10) and Sulphur Dioxide (SO2) Pollution Detection in Specified Regions of ？stanbul

In this study, we investigate the application of peak over threshold (POT) method on extreme events which usually appears with low frequently but high effects. Daily averages of PM10 and SO2 pollutants are measured at 5 permanent monitoring stations in ？stanbul (Be？ikta？, Yenibosna, Alibeyk？y, Esenler, Aksaray). The SO2 and PM10 concentration dataare obtained from ？stanbul Municipality through a period from January 2009 to December 2015.Daily averages of theconcentrations are analyzed by using peaks over threshold methods of extreme value theory and then predicted for the largest concentrations for the following 12 months. We find thatPOT methods can provide useful information about the occurrence of limit exceedances of air pollution in Istanbul and these models can easily be used to make short term predictions about limit exceedances.As a consequence, we can say that predicting the air pollutant levels of SO2 and PM10 will be beneficial for the decision makers which help them to develop advanced policies to control and prevent the air pollution
