International EISCAT Radar School
When: 17th – 21st August 2026
Where: Kilpisjärvi, Finland

The International EISCAT Radar School is a training course for new users of incoherent scatter radars at any stage of their research career. Participants should have a background in space physics, ionospheric pysics, plasma physics, or radar (radio science). The school will cover all essential aspects of the current incoherent scatter radar systems, including the science programme. An overview of the existing hardware and software was provided and future plans will be discussed, with an emphasis on phased array radars in preparation of EISCAT_3D.

The course will have a very strong emphasis on practicals, i.e. work in groups of participants on real data. There will be dedicated radar experiments for every group, and the groups will analyse their data and present their results under the guidance of an experienced team of instructors.

The radar school is organised by the Sodankylä Geophysical Observatory, the Space Physics and Astronomy Research Group (both University of Oulu), and EISCAT AB.

The radar school is part of the University of Arctic Thematic Network Arctic Space Hub.

The 22nd International EISCAT Symposium and the 49th Annual European Meeting on Atmospheric Studies by Optical Methods will take place after the Radar School, (more information here).

Old information video about EISCAT_3D and the importance of learning more about the interactions between the sun and the Earth.

First published in 2011.

With tens of thousands of satellites and millions of fragments in orbit, monitoring space debris is becoming increasingly important. Even small debris can interfere with scientific measurements, including studies of the aurora borealis and the ionosphere. EISCAT_3D will be able to detect debris down to a few centimetres and determine trajectories from a single observation, significantly enhancing EISCAT’s capabilities in space situational awareness.

The project, led by Johan Kero and Daniel Kastinen at IRF, strengthens EISCAT’s role as a key European research infrastructure. It not only expands the radar’s scientific applications but also supports international collaborations such as EU SST and the development of future radar systems like NOSTRA.

EISCAT releases a new version of GUISDAP.

GUISDAP is the main analysis package for the ionospheric EISCAT data, but parts can also be used for other types of analysis. It also contain extra tools like visualisation, calibration and vector calculation. With this version, support for phased array radar data, docker and packaging are introduced.

Please read the release notes for details.

22nd International EISCAT Symposium 2025 & 49th Annual European Meeting on Atmospheric Studies by Optical Methods

The Symposium is moved to 22-24 August 2026. Read more here: EISCAT Symposium 2026

The 22nd International EISCAT Symposium will occur the 18th – 22nd August 2025 in Kiruna, Sweden. The symposium will be joint twith the 49th Annual European Meeting on Atmoshperic Studies by Optical Methods.

The meeting will be hosted jointly by EISCAT AB and the Swedish Institute for Space Physics (IRF) at the Kiruna Space Campus.
