Global electron content: a new conception to track solar activity

We developed a method and programs for estimation of the global electron content (GEC) from GPS measurements, using the ionosphere models IRI-2001 and NeQuick. During the 23rd cycle of solar activity, the value of GEC varied from 0.8 to 3.2&times;10<sup>32</sup> electrons, followi...
