Short project summary

The project aims to initiate a new collaboration between the two research groups through a joint study into how energy is dissipated into the upper atmosphere through interaction between the Sun’s magnetic field (IMF) and the Earth’s magnetic field. Ultra Low Frequency (ULF) waves and turbulence manifest themselves as periodic fluctuations in the atmospheric signatures of this energy deposition (such as temperature and density changes) and in the Earth’s magnetic field. By monitoring the frequency, magnitude and location of the waves on the ground it is possible to investigate the complex plasma processes and interactions happening in the Earth’s ionosphere/magnetosphere system. The most intense wave activity in the ULF frequency range (from fractions of mHz to few Hz) is persistently observed at high latitudes. They are identifiable in ground based instrumentation such as magnetic field monitoring stations (magnetometers), optical equipment and radars. The instrumentation located on Svalbard at Longyearbyen, Barentsburg, Hornsund and Ny-Ålesund thus allows a unique opportunity to study these waves over long time periods at high latitudes.

This connection between the IMF and the Earth’s magnetic fields produces two main areas of interest which have two different physical methods of interaction.  These will be the focus of the collaborative projects. In addition, the project will also involve stays on Svalbard for researchers from IPE as well as joint fieldwork trips to Barentsburg. Researchers from UNIS will travel to IPE for joint workshops.

By monitoring changes in the Earth’s upper atmosphere (ionosphere), which is magnetically connected to the magnetosphere, we can understand the process of energy transfer between the two systems (adapted from Kivelson and Russel 1995).
