The graphical displays are by their nature public. They are meant to meet practical and scientific needs, and hopefully they are found inspiring by an scientifically interested audience. In case the displays are extensively used for commercial or scientific ends, the institutions which created the data will appreciate being contacted.

Digital data from DTU Space (Denmark, Faroe Islands and Greenland), GFZ and TGO in ASCII format are available here, but are protected by a password. Requests for password should be directed to DTU Space for Danish/Greenlandic data and to TGO for data from Norwegian magnetometers.
Data provided by GFZ are available through creative commons CC BY NC 4.0

We do not provide access to digital data from other magnetometers, please contact owners.

The IMAGE data base comprises data from most magnetometers from the Nordic Countries to Eastern Greenland. They are usually available there with a delay of a few months.

Some of the magnetometer stations are geomagnetic observatories (see list of stations). Data from these are submitted to the World Data Centres of geomagnetism. DTU Space and the Finnish institutions are also members of INTERMAGNET, TGO is not.

Commercial use of the data is welcome. Agreements must be made directly with the relevant institution.

The appearance and content of our open web-pages are subject to alteration without further notice. We accept no liability for loss or damages of any kind resulting from this or from errors or inaccuracies in the data.
