| Session Description | Rapid development of ground-based radio (IS radars, SuperDARN, GPS-TEC, Ionosondes etc.) and optical instruments during the last decade has allowed us to better visualize the dynamic nature of various ionospheric phenomena with improved spatial and temporal resolution. For example, recent extension of the SuperDARN network to both lower and higher latitudes has shown that the polar cap and mid-latitude ionosphere are much more active than we ever thought. In addition, there are several on-going ground-based and satellite (IMAGE, Cluster, THEMIS, REIMEI etc.) collaborations aimed at understanding the electromagnetic coupling between magnetospheric processes and ionospheric disturbances. This session addresses ground-based and satellite observations and data analysis as well as modeling approaches and theories of dynamics and structures in the high- and mid-latitude ionosphere, in terms of possible coupling between separate magnetospheric regions, the polar cap, cusp, auroral/subauroral zones, and mid-latitude ionosphere. Topics on the various kinds of ionospheric features, such as aurora, cusp auroral transients, polar cap aurora, ion outflow, polar cap patches, subauroral polarization stream (SAPS), magnetic pulsations, traveling ionospheric (atmospheric) disturbances, (TID/TAD), ionospheric irregularities (FAI), sporadic-E, and ionospheric storms, are welcome. Presentations on planned projects are also welcome. |
