Performance of International Reference Ionosphere-2016 and NeQuick-2 Models in Estimating Global Positioning System Total Electron Content Over a Nigerian Equatorial Station during Two Phases of Solar Cycle 24
Aim: This study examines the temporal behaviour of GPS-derived total electron content (GPS-TEC) and evaluates the capability of the International Reference Ionosphere-2016 (IRI-2016) and NeQuick-2 models to reproduce observed ionospheric conditions over Birnin Kebbi, Nigeria (12.64° N, 4.22° E; dip latitude 2.68° N).
