The EISCAT incoherent scatter radar system in northern Scandinavia, originally comprising a tristatic 931 MHz radar and a 224 MHz monostatic radar in the auroral zone, has expanded its geographical coverage poleward with the operation of the EISCAT Svalbard Radar (ESR) which began in 1996. In 1993 an HF-facility was incorporated in Troms\o~, allowing artificial perturbation techniques to be applied to ionospheric studies. The breadth of measurement capabilities will soon be expanded through the addition of a MST radar on Svalbard in 2002. We intend using the combination of these facilities to advance our understanding of the mesosphere and thermosphere. For example, the powerful HF facility near Troms\o~ can be used together with the radars for innovative studies of the ionosphere. By measuring the response of the ionosphere to electron heating, we can investigate the chemistry, dynamical processes and non-linear physics of the ionospheric plasma. Another technique now regularly applied is to use the decay of artificial periodic irregularities to study ion chemistry and vertical neutral wind motions down to about 50 km. The new combination of the SOUSY Svalbard MST radar and the twin-antenna ESR will enable us to study the interaction between the middle atmosphere and the ionosphere. In particular, the effect of solar proton events can be analyzed from their highest interaction altitudes with the atmosphere to their lowest. We show examples of ongoing and possible future research in all of these areas. Of course the SOUSY Svalbard Radar will also be used for studying dynamical coupling effects between the lower and the middle atmosphere.
