Variability of ionospheric ionization over Eurasia according to data from a high-latitude ionosonde chain during extreme magnetic storms in 2015

Autor: Chernigovskaya M. A., Setov A. G., Ratovsky K. G., Kalishin A. S., Stepanov A. E.

Publikováno v: Solar-Terrestrial Physics, Vol 10, Iss 2, Pp 34-47 (2024)

We have examined longitudinal-temporal variations in ionospheric parameters over Eurasia by analyzing data from a chain of high-latitude ionosondes along a latitude circle ~70° N (geomagnetic latitudes 58°

Effective subtraction technique: implementation for Irkutsk Incoherent Scatter Radar

Autor: Tashlykov V. P., Alsatkin S. S., Medvedev A. V., Ratovsky K. G.

Publikováno v: Solar-Terrestrial Physics, Vol 10, Iss 1, Pp 63-67 (2024)

For incoherent scatter measurements, the effective subtraction technique is to alternate the duration of amplitude-modulated signals between a pair of consequently radiated pulses. The resulting gain of spatial resolution enables us to steadily asses

Application of convolution neural networks for critical frequency fₒF2 prediction

Autor: Salimov B. G., Berngardt O. I., Hmelnov A. E., Ratovsky K. G., Kusonsky O. A.

Publikováno v: Solar-Terrestrial Physics, Vol 9, Iss 1, Pp 56-67 (2023)

Ionosphere has an important impact on the quality of radio communication, radar, and global positioning. One of the essential characteristics describing the state of the ionosphere is its critical frequency fₒF2. Its prediction provides effective m

Statistical relation of traveling ionospheric disturbances with neutral wind and disturbances in the stratosphere

Autor: Tolstikov M. V., Oinats A. V., Artamonov M. F., Medvedeva I. V., Ratovsky K. G.

Publikováno v: Solar-Terrestrial Physics, Vol 8, Iss 4, Pp 78-88 (2022)

Using the representative statistics on traveling ionospheric disturbances (TIDs) obtained by Yekaterinburg and Magadan radars, we have shown that distributions of TIDs and average TID velocities by azimuths and local time agree well with the hypothes
