AkalaA.O. 2201042The relative variability of peak electron density, NmF2 at equatorial and low latitude stations has been studied fairly well by workers in the past decade. A review of these studies is carried out in this work. The various methods used by workers, their merits and demerits are discussed. The results with respect to diurnal influence, seasonal effect and influence of solar cycle epochs, latitudinal dependence and effect of geomagnetic activity are synthesised and discussed. Areas requiring further investigation are mentioned.]]>Abdu, M.A., I.S. Batista, B.W. Reinisch and A.J. Carresco,20043419531965Akala, A.O., E.O. Oyeyemi, E.O. Somoye, A.B. Adeloye and A.O.
