**EISCAT** (**European Incoherent Scatter Scientific Association**) operates three [incoherent scatter](/wiki/Incoherent_scatter "Incoherent scatter") [radar](/wiki/Radar "Radar") systems in Northern [Scandinavia](/wiki/Scandinavia "Scandinavia") and [Svalbard](/wiki/Svalbard "Svalbard"). The facilities are used to study the interaction between the [Sun](/wiki/Sun "Sun") and the [Earth](/wiki/Earth "Earth") as revealed by disturbances in the [ionosphere](/wiki/Ionosphere "Ionosphere") and [magnetosphere](/wiki/Magnetosphere "Magnetosphere").

The EISCAT Scientific Association exists to provide scientists with access to incoherent scatter radar facilities of the highest technical standard.
