The ionosphere, which is a natural plasma, is a very important atmospheric layer in terms of radio wave propagation, located at an altitude of about 60 km to 1100 km from the Earth, consisting of ionized gases due to solar radiation. The ionosphere changes due to the effects of space and ground. That is, the change of the ionosphere layer depending on factors such as geographical location, day and night, season, solar activity, geomagnetic storm, earthquake has been the subject of many researches. Solar wind-induced geomagnetic storms change the earth's magnetic field. As a result of the pressure caused by the solar winds compressing the magnetosphere, the energy it contains increases. This plasma mobility causes an increase in electric current in the ionosphere. As a result, geomagnetic storms cause changes in ionospheric parameters. In this study, positive and negative storms in the ionosphere originating from geomagnetic storms were investigated. The anomaly calculation of the Total Electron Content (TEC) during the geomagnetic storms at different levels that occurred on March 7, 2016 and May 28, 2017 was examined with the help of statistical method using the upper and lower quadrants. These data are north pole stations, obtained by the Lowell GIRO Data Center; Calculated from TR169, YA462 and EI764 ionosonde data. In this way, ionospheric parameters (hmF2, f0F2, TEC) and space climate condition indices were determined for the dates determined, and the similarities and differences of polar ionospheric storms created by geomagnetic storms were investigated by comparing them.

6 Mart 2016 ve 28 Mayıs 2017’de meydana gelen farklı seviyelerdeki jeomanyetik fırtınaların özellikleri ve iyonosferde yarattığı pozitif ve negatif fırtınaları kuzey kutup istasyonları TR169, YA462 ve EI764 iyonosonda verileri sayesinde incelenmiştir. Bu sayede belirlenen tarihler için iyonosferik parametreler ve uzay iklim koşul indisler belirlenip jeomanyetik fırtınaların yarattığı kutupsal iyonosferik fırtınaların benzerlikleri ve farklılıkları karşılaştırılarak araştırılmıştır.
