In this study, we present the assessment of air pollution for the period 2007 – 2017 for the first five most polluting countries from each continent according to World Health Organization (WHO) and NUMBEO databases. Spatial variation of NO2 in each studied region is analyzed. Concurrent measurements of the NO2 pollution come from long-term satellite observations using the spaceborne instrument Ozone Monitoring Instrument (OMI). The satellite OMI instrument performs daily global measurements of NO2 using nadir Differential Optical Absorption Spectroscopy (DOAS) observations at a spatial resolution of 13x24 km2. Nitrogen dioxide data was extracted from OMI observations using Geospatial Interactive Online Visualization and ANalysis Infrastructure (GIOVANNI v4.24). The space observations represent the 30% cloud screened tropospheric vertical column densities of NO2 integrated over a surface of a binned pixel of 25x25 km2.
