INTERSECT studies effects of Space Weather events originating from the Sun on the ionosphere in 3 dimensions and in time (4D) by using an ambitious combination of measurements and modelling. The key instruments will be the current EISCAT incoherent scatter radar facilities, the new EISCAT_3D radar starting operations during the first year of the project, TomoScand ionospheric tomography, optical measurements, several international satellite missions, and Finland's own Suomi 100 CubeSat. The measurements are combined with state-of-the-art simulations of the ionosphere, which is coupled with the thermosphere, magnetosphere and the solar wind. Radio wave propagation in the disturbed ionosphere is studied with first principles simulation based on Maxwell equations. The project will result in new quantitative information on the causes and consequences of those processes that cause ionospheric storms in the Arctic region and may disturb satellite navigation and communication.
