The topside sounding experiment (PPS) on board the EXOS-C (OHZORA) satellite has been successfully carried out in the ionosphere for the observation of plasma structure and its variation as well as the plasma wave phenomena due to the plasma turbulence associated with the precipitating particles. The satellite has the initial apogee and perigee of 865km and 353km, respectively, with the inclination of 74.6°. The PPS observations have presented following new data and evidences. (1) Very intense electrostatic plasma waves as well as the whistler mode waves have been observed as a result of the particle precipitation into the ionosphere. At the same time the satellite observed the small scale irregularities in the high altitude, which suggests the plasma turbulence produced by the particle precipitation through the wave particle interaction process. (2) The up-ward movement of the ionospheric plasma due to the local thermalization has been observed in the trough region, being associated with the particle precipitation. An aspect that the particle precipitation injects energy into the polar ionosphere has also been confirmed. (3) Latitudinal dependency of the scale height above the F_2 peak altitude has been detected by analyzing the vertical profile of the electron density deduced from the echo data. The temperature deduced from the scale height indicated the evidence of the heat input into the low latitude ionosphere across the magnetic field. (4) The leaked auroral kilometric radiation has been successfully observed in the polar ionosphere. These observation data strongly support the conversion theory of the generation process of auroral kilometric radio waves. It is also newly discovered that the leaked AKR waves show a very fast variation in their intensity. |
