Over 30 years of EISCAT radar measurements at Tromso are analyzed to determine various ionospheric and thermospheric parameters at high latitude. Plasma momentum equations are used to derive field-aligned electric fields and currents, as well as thermospheric density, from the observations. The results will be presented focusing on solar-cycle variations and long-term trends. The validity of the techniques will be also discussed.
