Over the past few decades, rapid developments in space technology have advanced the research of ionospheric space weather by increasing a great number of ground- and space-based observations. 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 with payloads onboard the satellites providing radio occultation soundings of vertical electron density structure and in-situ observations of airglow, temperature, neutral winds, and electron density contribute to the understanding of middle and upper atmospheric dynamics. With the large amount and diversity of datasets, theoretical and empirical models can be validated and implemented for inclusion of new thermosphere and ionosphere phenomena. Furthermore, remarkable breakthrough of data assimilation techniques advances the ionosphere monitoring and forecast. The recent innovations in observations and models reinterpret the studies of ionospheric space weather. The purpose of this session is to solicit studies providing observations, theoretical and empirical modeling and data assimilation on the multiple scales of ionospheric phenomena, from global morphology to small-scale irregularities and traveling ionospheric disturbances. Studies on magnetically quiescent and disturbed conditions will be both addressed.
