Geomagnetic time series

The time series are available within the framework of the Nordic Virtual Observatory project. This collaboration of Tromsø Geophysical Observatory (TGO), the Finnish Meteorological Institute (FMI), Sodankylä Geophysical Observatory (SGO), and the Swedish Institute of Space Physics (IRF) intends to achieve a higher degree of effectiveness in observations related to external geophysics and to operate a centralized visualization and dissemination of regional core data via the Nordic Space Weather Situation Screen.
