A radio wave of frequency just above the MUF may suffer a partial ducting when propagating into an ionospheric layer with a decreasing horizontal grad Cited by: 5.

Ionospheric and magnetic disturbances may be accompanied by visible auroras. Solar radiation is not constant by any means. In Fig. 1, panel 6 represents the PROMICS-3 low energy ions measured by the D3 singly four clear dispersion ramps can be identified. The first one commencing at UT is characterized by intense particle flux with mean energy E ≈ 1 dispersion of this proton event is the steepest one and the whole duration is min.

Before performing the cross correlation, the electric field data were linearly interpolated and resampled at the same 1 s time rate as the magnetic field data.

It would help a lot if you send entries in the same style as those already in the listings. In Section of this chapter, we examine carefully whether the observed magnetic field disturbances Δ B (X, Y, Z) at various points in the magnetosphere during substorms are consistent with those which we expected from the diverted cross-tail : Syun-Ichi Akasofu. 1 Introduction. Ionospheric disturbances caused by solar flares and solar energetic particles are known to disrupt high‐frequency (HF, 3–30 MHz) transionospheric radio systems, including HF communication systems used in aviation, maritime, and emergency management, as well as over‐the‐horizon radars used in applications such as ionospheric research, coastal hazard management, and Cited by: 4.
