been developed using the NeQuick ionospheric electron density model driven by its effective ionization parameter
Az. The technique is based on the computation of Az values for a suitable worldwide grid of points. A simple
way to obtain relevant Az grids is to use global vertical Total Electron Content (TEC) maps to define for each
grid point as Az value, the one that minimizes the difference between the experimental and the modeled vertical
TEC. Having a global grid of Az values it is possible to compute the electron density at any point in the ionosphere
using NeQuick. As a consequence, slant TEC values for specific ground station to satellite links or ionosphere
peak parameter values at any location can be calculated. The results of the comparisons between experimental
and reconstructed slant TEC as well as experimental and reconstructed peak parameters values indicate
that the proposed reconstruction method can be used to reproduce the observed ionosphere in a realistic way.
