in space technology are advancing our understanding of ionospheric space weather
by increasing a great number of ground- and space-based observations over the
recent decades. In the ground segment, the dense ground-based GNSS networks,
radars, and airglow instruments have greatly extended the observational
coverages. In the space segment, the extraordinary satellite missions, such as
FORMOSAT-7/COSMIC-2, ESA-SWARM NASA-ICON and -GOLD, providing a variety of
observations all over the world such as airglow, temperature, neutral winds,
current, ion drifts, plasma density that contribute to the understanding of
middle and upper atmospheric dynamics. Increasing ground-based observations are
also important for coordinations with these satellite missions.</span></p><p class="MsoNormal" style="text-align:justify;margin:0cm 0cm 0.0001pt;font-size:12pt;font-family:"Times New Roman",serif"><span lang="EN-US">With the large
