Session 2 Short and long-term variations of the ionosphere and plasmasphere (including multi-instruments and modelling)
As the polar regions are Earth's windows to outer space, they provide a unique opportunity for scientific research of the direct connection of the Earth with the geospace, which is not possible at mid and low latitudes. The ionospheric plasma following the magnetic field lines in the polar regions can escape to the magnetosphere. The ionosphere-plasmasphere-magnetosphere layers constitute a dynamic and coupled system being permanently influenced by the neutral atmospheric processes from below (troposphere and stratosphere) and by the space phenomena from above (solar activity, particle precipitations, interplanetary magnetic field, ….).
The polar ionosphere-plasmasphere-magnetosphere system is not as well understood in the Antarctic/Arctic regions, as compared to other regions due to a lack of experimental observations. This session aims to present the up-to-date knowledge on ionospheric, plasmaspheric and magnetospheric physics at high latitudes and their coupling. These studies can be from short-term (i.e. hours to days associated with geomagnetic disturbed periods) to long-term scales (seasonal and years, i.e. climatology). This session also is the opportunity to discuss the different results based on physical or empirical models, satellite data (i.e. Cluster, Swarm, CubeSat PICASSO, COSMIC …) or as well as ground-based data sets (i.e. ionosondes, magnetometers, GNSS, VLF, EISCAT, …).
