Abstract

An examination of analysis revealed that surface ozone concentration over Nigeria varied with direction of the local trade winds, namely the Harmatan, and the Gulf of Guinea maritime trade winds. In DJF and MAM the period of the dry dusty Harmatan seasons, surface ozone concentration in the southern Nigeria exceeded that of the north by 21DU and 24DU respectively. Whereas in the JJA and SON, the rainfall season, reversal was the case, the surface ozone concentration in the northern Nigeria exceeded that of the south by 20DU and 15DU respectively. Maximum temporal variation gradient of 20DU was also observed in MAM season while the minimum of 11DU occurred in JJA which is the peak of the raining season. Keywords: Surface ozone concentration, spatial gradient, temporal gradient.
