Ionospheric response to the weak geomagnetic storm of 1–2 February 2025 in the Weddell Sea Anomaly region: observations from Ukrainian Antarctic Akademik Vernadsky station

open access: yesУкраїнський антарктичний журнал
The ionospheric response to the weak geomagnetic storm of 1–2 February 2025 was studied within the Weddell Sea Anomaly region. The behavior of the key ionospheric parameters (NmF2 and hmF2) was analysed using ionosonde observations from the Ukrainian ...

Satellite Traces: Ionogram Signatures of Bottom‐Side Upwelling Structures ‐ A Simulation Study

open access: yesGeophysical Research Letters
Satellite Traces (STs) are the important ionogram signatures for the presence of upwellings in the bottom‐side ionosphere, which provide the necessary seed perturbation for the development of equatorial plasma bubbles (EPBs).
