Abstract
Diurnal variation of vertical total electron content (VTEC) over Lagos, Nigeria (6.52° N, 3.399 E, dip latitude 3.03° S) during low solar activity period (2010) and a comparison with NeQuick-model-derived VTEC, are presented in this paper. VTEC generally increases from 0600 h LT and reaches its maximum value at approximately 1400 to 1700 h LT during all months considered. Our result shows that NeQuick model provide a good prediction during daytime and nighttime at Lagos, although some improvements are still required in order to have increase navigational accuracy for single frequency Global Positioning System (GPS) receivers. The pre-sunrise and noontime deviations between modelled and observed VTEC could arise because either the peak electron density of the F2 region (NmF2) or the shape of the electron density profile, or both, are not well modelled.
