Comparison of the measured values of total electron content (TEC) with the corresponding TEC values, obtained according to global ionopheric maps (GIM) data
The purpose of this work lies in comparing and defining the differences between the measured values of the total electron content (TEC) and the corresponding TEC values, obtained according to global ionospheric map (GIM) data in different periods of solar activity. Methodology. The TEC and the data of global ionospheric maps (GIM) for the SULP station were used in the work, as well as the data from the Ionolab website for better clarity, where the nodal values of the TEC are essentially used, from the same global ionospheric maps (GIM).
