Air quality data used in this study provided by Malaysia Department of Environment (DOE). A total of 14,608 daily mean of PM 10 and meteorological parameters (humidity, temperature and wind direction) data from 2006 to 2015 at eight Continuous Air Quality Monitoring (CAQM) stations in Klang Valley are used in this study. Statistical Package for the Social Sciences (SPSS) and ArcGIS 10.4 software are used in this study to apply the descriptive statistical and spatial trend of this PM 10 concentration. The result showed that increasing of PM 10 concentration are being observed in Southwest monsoon and decreasing during Northeast monsoon. The Ordinary Kriging distribution map shows that the station located at urban and industrial area will have higher PM 10 concentration as compared to the station that is located in the rural area. The spatial interpolation method, Ordinary Kriging was used to interpolate the PM 10 concentration outside the station’s range.
