EISCAT

EISCAT is an international scientific research infrastructure that specialises in measurements of the atmosphere and the ionosphere, i.e. the upper part of the atmosphere, using scattering radar systems. EISCAT produces observational data for researchers in the fields of the northern lights, space weather and plasma physics, for example. EISCAT provides a robust and high-quality database of ionospheric measurements by developing and maintaining observation activities in cooperation with other ground station and satellite measurement operators. EISCAT operates as part of a global network of scattering radars.

EISCAT has radar stations in Svalbard and Tromsø, Norway. A new EISCAT 3D scattering radar system is under construction, with radar stations located in Kaiseniemi in Sweden, Skibotn in Norway and Karesuvanto in Finland.

In Finland, EISCAT research activities are coordinated by the Sodankylä Geophysical Observatory of the University of Oulu.

EISCAT is operated by EISCAT AB, whose shareholders are the states of Sweden, Norway and Finland in equal shares. In Finland, EISCAT AB's ownership steering is the responsibility of the Academy of Finland. In addition, the United Kingdom and Japan are involved in the company's operations.
