Аннотация
The results of ~100 sessions of sounding of the Earth’s high-latitude (>65° N) ionosphere performed on June 22–23, 2015, at a GPS carrier frequency of f1 = 1575.42 MHz (L1 range, wavelength of ~19.0 cm) in the FORMOSAT-3/COSMIC radio occultation experiment are analyzed. The coronal plasma ejections that reached the Earth’s magnetosphere during this time period provoked a strong magnetic storm of the G4 class (G4 = Kp – 4), which caused significant fluctuations in radio wave parameters on ionospheric sounding paths: navigation (GPS) satellites—low-orbit (FORMOSAT-3/COSMIC) satellites. Ionospheric disturbances in the characteristics of radio waves are shown to be caused by both geomagnetic conditions and the activity of powerful X-ray flares during measurements. A search for the absorption of decimeter radio waves (wavelength of ~19 cm) at a GPS carrier frequency of f1 = 1545.42 MHz was carried out. Based on the results of the FORMOSAT-3/COSMIC data analysis, an integral absorption of ~3 dB of decimeter radio waves was detected for the first time on the sounding paths in the D and E regions of the Earth’s high-latitude ionosphere.
