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.

    Statistical characteristics of medium-scale traveling ionospheric disturbances revealed from the Hokkaido East and Ekaterinburg HF radar data

    We present a statistical study of medium-scale traveling ionospheric disturbances (MSTIDs) using the Hokkaido East (43.53° N, 143.61° E) and Ekaterinburg (56.42° N, 58.53° E) high-frequency (HF) radar data. Ra...

    Daytime gigahertz scintillations near magnetic equator: relationship to blanketing sporadic E and gradient-drift instability

    Observations made in non-equatorial regions appear to support the hypothesis that the daytime scintillation of radio signals at gigahertz (GHz) frequencies is produced by the gradient-drift instability (GDI) i...

    Strong induction effects during the substorm on 27 August 2001

    We report on strong induction effects notably contributing to the cross polar cap potential drop and the energy balance during the growth and active phases of the substorm on 27 August 2001. The inductance of ...

    Application of ground scatter returns for calibration of HF interferometry data

    Information on the vertical angle of arrival (elevation) is crucial in determining propagation modes of high-frequency (HF, 3–30 MHz) radio waves travelling through the ionosphere. The most advanced network of...

    Method for modeling of the components of ionospheric parameter time variations and detection of anomalies in the ionosphere

    In this study, a new multicomponent model (MCM) to determine the time variation of ionospheric parameters is suggested. The model was based on the combination of wavelets with autoregressive-integrated moving ...
