Abstract
Bu çalışmada, NmF2 verileri (51,70 °K; 358, 67 °D) coğrafik koordinatlarda Chilton istasyonunda medyan olarak ölçüldü. Bunun yanısıra NmF2 değerleri aynı coğrafik koordinatlar için IRI-2001 modeli kullanılarak elde edildi. Ölçülen ve hesaplanan değerler mevsimsel ve yıllık olarak karşılaştırıldı. Ölçülen ve hesaplanan maksimum elektron yoğunluğu değişimleri mevsimsel ve yıllık olarak araştırılmıştır. Iyonosferin F2-bölgesinde ölçülen ve hesaplanan maksimum elektron yoğunluğu arasında tam bir uyum vardır. Bu uyum, korelasyon katsayısı ile verilmiştir.
