چکیده
A_j2_S.I!20g• Limb-scan observations of Doppler line profiles from the O+(2P) X732.0 nm emission atF-region altitudes, made with the Fabry-Perot interferometer (FPI) on the Dynamics Explorer-2 (DE-2) spacecraft, have been analyzed to provide measurements of the meridional component of the ion convection velocity along the instrument line-of-sight The initial DE-2 results presented here demonstrate the first spaceborne use of the remote-sensing Doppler technique for measurements of ionospheric onvection. The FPI meridional ion drift measurements have been compared with nearly simultaneous in-situ ion drift measurements from the

First measurements of radar coherent scatter by the Radio Aurora Explorer CubeSat
[1] The Radio Aurora Explorer CubeSat detected the first radar echoes during the solar storm of March 8, 2012. The 300 s ground-to-space bi-static radar experiment was conducted in conjunction with the Poker Flat Incoherent Scatter Radar in the local morning ( 8 am) over Poker Flat, Alaska. The geomagnetic conditions for the E region field-aligned irregularity generation were optimal due to str...
متن کاملVHF coherent radar signals from the E region ionosphere and the relationship to electron drift velocity and ion acoustic velocity
[1] The Scandinavian Twin Auroral Radar Experiment (STARE) coherent radar system measures the Doppler shifts caused by 1 m plasma waves in the high-latitude E region ionosphere. These Doppler velocities are here related to the electron drift velocity and ion acoustic velocity derived from measurements with the incoherent radar system European Incoherent Scatter (EISCAT). The Doppler velocity is...
