| Zusammenfassung |
| The disturbances of very low and low frequency signals in the lower mid-latitude ionosphere
caused by magnetic storms, proton bursts and relativistic electron fluxes are
investigated on the basis of VLF–LF measurements obtained in the Far East and
European networks. We have found that magnetic storm
(−150 < Dst < −100 nT) influence is not strong on variations of
VLF–LF signals. The anomalies with negative amplitude were registered during
the main and recovery phases for several magnetic storms (mainly for three
northernmost paths). The correlation between VLF–LF signals and geomagnetic
activity is rather weak even for these paths (≈ 12–18%). Also,
the correlation between magnetic activity and VLF signal variations recorded
onboard the DEMETER satellite is not found. The significant influence of
outer-zone particles (energetic particle sensor on board/Geostationary Operational Environmental Satellite (GOES) measurements) on the VLF–LF signal variations
is found for almost half of the sub-ionospheric paths. |
