The NIGTEC is a model of the ionospheric GNSS TEC over Nigeria (Longitudes 2-15 degrees East, Latitudes 4-14 degrees North)
The model can be used to obtain the ionospheric GNSS TEC at all locations over Nigeria.
For this version of the model (version 1.2), usage is encouraged to be restricted between years 2010-2023. There is plan to update the model biennially. The year span of encouraged usage will be expanded in subsequent versions of the model.
The model is developed by the method of artificial neural networks as detailed in the full paper which is on open access at: http://dx.doi.org/10.1016/j.geog.2016.03.003 and also included in the model folder
