Abstract

Magnetic storm which occurred on 08.09.2017 was analyzed on the basis of the TEC values obtained by GNSS measurements. TEC values were obtained from the RINEX observations of GNSS stations in different regions of the ionosphere in the north and south poles. In order to reveal the magnetic storm-induced TEC change, a total of 12-day data for each station, 10 days before the magnetic storm, the magnetic storm day and after the day of magnetic storm were evaluated. As a result of the analysis, positive and negative anomalies were obtained before and after the magnetic storm. As a result of this study, it is shown that ionospheric variations caused by magnetic storm can be determined using GNSS observations.

Özet

08.09.2017 tarihinde gerçekleşen manyetik fırtınanın iyonosfer tabakasında sebep olduğu değişim, GNSS ölçülerikullanılarak elde edilen TEC değerleri üzerinden analiz edilmiştir. Kuzey ve güney yarımkürede, iyonosferin farklıbölgelerinde bulunan GNSS istasyonlarına ait RINEX gözlemlerinden TEC değerleri elde edilmiştir. Manyetikfırtına kaynaklı TEC değişiminin ortaya çıkarılabilmesi için manyetik fırtına öncesi 10 gün, manyetik fırtına günüve sonrası 1 gün olmak üzere her istasyona ilişkin toplam 12 günlük veri değerlendirilmiştir. Yapılan analizsonucunda manyetik fırtınanın olduğu gün, öncesi ve sonrasında pozitif ve negatif anomaliler elde edilmiştir. Buçalışma sonucunda Türkiye’de bulunan GNSS istasyonları kullanılarak manyetik fırtına kaynaklı iyonosferdeğişimlerinin tespit edilebileceği gösterilmiştir.
