  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.
