P(論文) Using Antarctic rockets S-310JA-4 and S-310JA-6 launched respectively on August 18 and August 27 in 1978,plasma waves in the MF and HF frequency range, i.e., from 0.1MHz to 10MHz have been observed in the polar ionospheric level up to 230km. Four categories of the plasma wave emissions are ide...

Four categories of the plasma wave emissions are identified in consideration of the correlation with the energetic particles data. The first is the subsidiary emissions that are enhanced in the form of the ESCH (electrostatic electron cyclotron harmonic) waves due to the energetic electron beams in 2keV range; the emissions are generated in a regime of the nonlinear wave particle interactions because of the effective growth rate of the ESCH waves. The second is the ESLEC mode waves. The electrostatic plasma waves in the frequency range lower than the electron cyclotron frequency are called ESLEC mode waves in this paper; the generation of ESLEC mode wave is caused by the loss-cone type velocity distribution of the particles without any significant relationship to the electron beams in auroras. The third is the wide-band emission that can be attributed to the continuum emission emanating from the upper side of the ionosphere located below the rocket position; there still remains a possibility of the celestial radio waves arriving from the outside of the earth. The fourth is the leaked auroral kilometric radiation (AKR), propagating down towards the ionosphere in the form of the whistler mode waves. The waves have no one-to-one correspondency to the in situ observations of the precipitating particles, but the source is located in the region of the auroral particle accelerations where the AKR is generated. departmental bulletin paper Other/Unknown Material Antarc* Antarctic Memoirs of National Institute of Polar Research Polar Research National Institute of Polar Research Repository, Japan Antarctic The Antarctic
