Urban pollution in urban cities in developing countries is high because of overwhelming concentration of vehicles, poor transport infrastructure, biomass burning, use of fossil-fuel engines and citing industrial parks close to residential building. A fifteen years dataset was obtained from the Multi-angle Imaging Spectro-Radiometer (MISR). Computational and statistical analysis was adopted. The percentage of increase of aerosols loading was high in 2002, 2006, 2008, 2009, 2010 and 2011 which was 38.5%, 22.9%, 11.8%, 19.2% and 63.2%. Cumulatively increase of aerosol loading within 15 years was 15.0%. These results show that the annual aerosol loading of the Yaoundé atmosphere has far exceeded the WHO limits.
