Short summary
The study examined the diurnal and seasonal variations in total electron content (TEC) over Nigeria. The derived GPS TEC across all the stations demonstrated consistent minimum diurnal variations during the pre-sunrise hours, increased with a sharp gradient during the sunrise period, attained a postnoon maximum at about 14:00 LT, and then fell to a minimum just before sunset. The seasonal variation depicted a semi-annual distribution with higher values around equinoxes than solstices.
