Short summary

Based on hourly averages of the total electron content (TEC), a regional model of the TEC was constructed. Annual averages calculated from monthly medians of the detrended TEC were used to estimate any trends in the TEC over the African low latitudes. A predominantly negative trend in the ionospheric TEC was observed in the vicinity of the dip equator.
