The high-latitude ionosphere is one of the most affected regions of the Earth’s space environment particularly during periods of high solar activity. Because of this, vast numbers of ground-based radio (IS radars, SuperDARN, GPS receivers, Ionosonde, ground-based magnetometers etc.) and optical instruments have been deployed during the last decade to better visualize the dynamic nature of various ionospheric phenomena with improved spatial and temporal resolution. In addition, there are several on-going ground-based, satellite (Cluster, THEMIS, Geotail etc.) and rocket collaborations aimed at understanding the electromagnetic coupling between magnetospheric processes and ionospheric disturbances. This session focuses on observational, theoretical and modelling aspects of high-latitude ionospheric dynamics, including micro- and macro-scale physics of aurora, ionospheric plasma motion, field-aligned currents, generation of waves, instabilities, turbulence and scintillation phenomena and other processes. Presentations on planned projects are also welcome.
