Geomagnetic storms (GS) significantly affect ionospheric variability and state of ionization. The irregular processes occurring in the ionosphere exert influence on modern HF technologies both in outer space, for example, on satellites, and on Earth-based infrastructures such as radars, navigation systems and radio communications. Therefore, understanding and modeling the effect of GS on variations of various ionospheric parameters is extremely important for applied purposes. This study presents the response of the European midlatitude ionosphere on the intense GS of September 6–10, 2017. This GS was caused by coronal mass ejections (CMEs) launched on September 4th and 6th. The monitoring of the ionosphere state was conducted using the data obtained from the ionosonde and Kharkiv incoherent scatter radar (ISR) (49.6ºN, 36.3ºE). The height profiles of electron temperature (Te), variations in the F2 peak electron density (NmF2), height (hmF2) and critical frequency (foF2) were analyzed. Significant changes in these parameters were found. In addition, we described the wavelike events related to the propagation of traveling ionospheric disturbances (TIDs) which could be initiated by GS, as well as estimated their vertical and horizontal propagation parameters. We also discussed our results and made comparisons with the other studies of the ionospheric response to this storm.

摘要

Geomagnetic storms (GS) significantly affect ionospheric variability and state of ionization. The irregular processes occurring in the ionosphere exert influence on modern HF technologies both in outer space, for example, on satellites, and on Earth-based infrastructures such as radars, navigation systems and radio communications. Therefore, understanding and modeling the effect of GS on variations of various ionospheric parameters is extremely important for applied purposes. This study presents the response of the European midlatitude ionosphere on the intense GS of September 6–10, 2017. This GS was caused by coronal mass ejections (CMEs) launched on September 4th and 6th. The monitoring of the ionosphere state was conducted using the data obtained from the ionosonde and Kharkiv incoherent scatter radar (ISR) (49.6ºN, 36.3ºE). The height profiles of electron temperature (Te), variations in the F2 peak electron density (NmF2), height (hmF2) and critical frequency (foF2) were analyzed. Significant changes in these parameters were found. In addition, we described the wavelike events related to the propagation of traveling ionospheric disturbances (TIDs) which could be initiated by GS, as well as estimated their vertical and horizontal propagation parameters. We also discussed our results and made comparisons with the other studies of the ionospheric response to this storm.
