Simultaneous ground-satellite observations of ELF-VLF emissions have been carried out at Syowa Station (L~6) in Antarctica during the IMS period by receiving the telemetry signals from the ISIS 1 and 2 satellites. The quasi-periodic intensity modulation of ELF-VLF emissions at the satellite level, which had one-to-one correspondence with the intensity modulation of QP emissions at Syowa, was observed in the wide latitude range from -54¿ to -78¿ MLAT, and also in the region ~2 hours apart from Syowa in magnetic local time. The spectral form of QP emissions observed on the ISIS satellite showed a clear dependence on latitude, i.e., emissions in the higher frequency range were observed at lower latitudes, while emissions in the lower frequency range were observed at higher latitudes. Although quasi-periodic intensity modulation of polar chorus had generally one-to-one correspondence between the ground and satellite data, burst-like discrete emissions did not show always one-to-one correspondence between both data. These results give a basis to confirm a phenomenological model proposed by Sato and Fukunish [1981> for the generation mechanism of QP emissions. |
