This work aims to study the regular variations of the ionosphere at middle and low latitudes and the impact of various events on solar ionization. To quantify these changes, we will use GPS networks to measure the Total Electronic Content (TEC) .This work is part of the project ISWI. The study will include a morphological analysis on regular variations in the ionization time of the Quiet Sun (diurnal variation, seasonal and based on the solar cycle) for the treatment of GPS stations in Europe and Africa over the period analyzed (2000 to 2014); variations disturbed ionosphere associated with solar events selected according to a set of criteria; Analysis of the ROTI index to study the ionospheric scintillation generating degradation position...
