Tromsø Geophysical Observatory: Earth's Magnetic Field Monitoring

Visit the Tromsø Geophysical Observatory, a department of the University of Tromsø, maintaining long-term observations of the Earth’s magnetic field and ionosphere in a global geophysical context. The observatory's staff includes 2 scientists and 3 engineers who oversee a variety of instruments in the auroral zone, such as magnetometers, ionosonde, meteor wind radars, and VHF MST radar. With a magnetometer network spanning the Norwegian mainland and arctic area and extensive ionospheric data dating back to 1935, TGO contributes significantly to the field of geophysics. The observatory is involved in collaborations worldwide, including projects like AFFECTS, ensuring competent data assimilation and delivery.

  1. TromsøGeophysicalObservatory A department of the University of Tromsø Maintaining long term observations of the Earth’s magnetic field and ionosphere in a global geophysical context Staff of 2 scientists and 3 engineers

  2. Instrument park • We take care of a variety of instruments in the auroral zone – some our own, some as collaborations and some for guests • Instruments include: • Magnetometers • Ionosonde • Meteor wind radars • VHF MST radar

  3. Magnetometers Magnetometer network with over 20 instruments on the Norwegian mainland and arctic area including collaborations on Greenland and south Atlantic. Measurements date from 1912

  4. Ionosonde Ionospheric data since 1935 – one of the three longest existing datasets in the world. Today’s instrument, a collaboration with the UK, gives information on electron density in the atmosphere several times every hour.

  5. TGO in the context of AFFECTS Magnetometers at several locations spread over the whole map Ionosondes at Tromsø (TGO/QinetiQ) and Longyearbyen (EISCAT). Project includes upgrade of Longyearbyen antenna. Competance in working in the field, data assimilation and delivery Contribution comprises delivery of data from these instruments and channelling / “helping” data from the other instruments to the respective databases.
