Abstract: In this study, regional air pollution across Nigeria was studied for five criteria air pollutants. The pollutants are carbon Monoxide (CO), Sulphur Dioxide (SO2), Ozone (O3), Aerosol Optical Depth (AOD) at 550nm, and Nitrogen Dioxide (NO2).These criteria air pollutant were assessed from NASA GIOVANNI air quality platform. The data obtained was analyzed using a time series analysis. Three of the variables, CO, NO2 and SO2 showed a slight decline in the concentration of pollutants across the years. A Principal Component Analysis (PCA) statistics conducted in the study revealed that annual CO, NO2 and SO2 were positively correlated while AOD showed a very weak correlation with CO, SO2 and NO2. Ozone negatively correlated with all other variables. A Hierarchical Cluster Analysis (HCA) conducted grouped the pollutants into two major groups which agreed with the Principal Component Analysis (PCA) which grouped the pollutants into two component.
