The aim of this study is to examine the characteristics of the tropospheric Nitrogen Dioxide (NO2) concentrations over the five states of South Eastern Nigeria retrieved from Ozone Monitoring Instrument (OMI) data from 2010 â€“ 2015. The mean concentration ranges fromÂ Â molecules/cm2 in Abakaliki (with the least commercial, industrial and vehicle activities) toÂ Â in Aba, the industrial and commercial centre with coefficients of variation of 17.7% and 15.8% respectively. Results using non-parametric Mann-Kendall (MK) tests show a significant (p
