| Research Abstract |
EISCAT radars are one of the greatest tools in the world for observing ionospheric phenomena in the auroral, polar cusp and cap regions. EISCAT radar systems provide us with essential physical parameters over the polar ionosphere. Solar-Terrestrial Environment Laboratory (STEL) has been playing a central role in promoting a variety of research projects using the ESR and KST radars of the EISCAT Scientific Association. Both STEL and NIPR, in collaboration with researchers across the nation, have conducted about 50 Special Program (SP) experiments such as Magnetosphere-Ionosphere coupling process using simultaneous observations by REIMEI satellite and EISCAT, DELTA-2 rocket campaign, vertical wind in the lower thermosphere, wind dynamics in the lower thermosphere, ion upflow, and aurora phenomena. In the result of these activities, 29 papers have been published for 4 years.
