[PEM10-26] Study on ion upflow based on high latitude IS radars and future EISCAT_3D
The ion upflows have been investigated with incoherent scatter (IS) radars at high latitude. Future EISCAT_3D is one of the most suitable measurements to investigate such transitions because of its wider height coverage (up to about 2000 km) along the field line. EISCAT_3D will have more transmitter power density and higher sensitivity than those of the current IS radars at high latitude, and will give information of accurate thermal ion velocity, upward flux, and ion composition (O+, H+, and hopefully NO+). A combination of the EISCAT_3D, ground-based optical instruments, and in-situ measurements is definitely essential to solve several key questions of ion upflow and outflow study. In this paper, we show potential investigations of ion upflow and outflow using the EISCAT_3D, and also discuss a desirable combination of the EISCAT_3D and its related observations for the ion upflow and outflow study.
