SGO Riometer measurements

Finnish Riometer Chain

Today the Finnish Riometer Chain includes observations from the novel spectral riometers and traditional La Jolla riometers at Kevo, Abisko, Ivalo, Sodankylä, Rovaniemi, Oulu and Jyväskylä. In addition to thse SGO hosts two ISEE spectral riometers located to KAIRA station Kilpis&j&aumrvi and Oulujärvi geomagnetic observatory. KAIRA LBA antenna array are used for the riometer application. The Imaging Riometer IRIS in Kilpisjärvi suffered a hardware failure in July 2023. It was operated in collaboration with the University of Lancaster (UK) since 1994.

SGO riometer observations (David Andersson riometers) started in 1965. Early years riometers in Vidsel and Abisko (Sweden), in Ramfjord (Norway) and in Hornsund (Svalbard) were operated in collaboration with the University of Lancaster (UK).
