Studying the Relationship between TEC, I95 Index and Wp Index and Affect Them on Ionosphere in Iraq, Romania and South Africa

—This article study the state of Ionosphere in some continents across the world, spots had been chosen in South Africa, Europe, and Asia. The Ionosphere in these spots are so different and they have different TEC because they are located different coordinates in Longitude and Latitude in the Earth. The Ionosphere has activity points based on the solar wind and another parameter, this can affect the signal that transmitted from the ground station to the Satellites. This article has been used some programs that simulated the perturbations because of the activity in the Ionosphere, Three different models have been used, Nequick model, IRI Plaz-2017 and Trignet from 0 to 1000Km. The goal of this paper to study the Ionosphere with different indices to confirm the disturbance of the Ionosphere. Nequick model at 2016, 2018 for IRI-Plaz 2017 and 2018 for Trignet the date for study. These results produce that the Ionosphere activity and conductivity for reflection signals are hard in the Equatorial region compared to the Poles.
