Coupling of the High and Mid Latitude Ionosphere and Its Relation to Geospace Dynamics

Edited by N. Nishitani, T. Nagatsuma, A. S. Yukimatu, H. Hu, T. Sakanoi

This special issue originates from the ST-20 session "Coupling of the High and Mid Latitude Ionosphere and Its Relation to Geospace Dynamics," held during the AOGS 2014 Meeting in Sapporo. Papers are also presented by authors who did not attend the meeting. This special issue is focused on the coupling of the high and mid latitude ionosphere, which play important roles in geospace dynamics. Recently, the coverage offered by ground-based observation networks (magnetometers, HF radars, GPS receivers etc.) has dramatically increased, allowing us to better understand the coupling between the high and middle latitude ionosphere. In addition, many satellites in geospace also provide essential in-situ data, yielding many new findings and posing new questions. These papers contribute to our understanding of middle-high latitude ionosphere and geospace coupling, and of geospace dynamics.
