[P-EM14] Recent Advances in Ionosphere Observation and Modeling for Monitoring and Forecast

Thu. May 24, 2018 3:30 PM - 5:00 PM 301B (3F International Conference Hall, Makuhari Messe)

convener:Charles Lin(Department of Earth Sciences, National Cheng Kung University), Yang-Yi Sun(China University of Geosciences, Institute of Geophysics and Geomatics), Chairperson:Lin Charles, Sun Yang-Yi

Increasing number of observation opportunities in the Earth's ionosphere and upper atmosphere advances the research of the ionosphere weather in the recent two decades. In the ground segment, global deployment of ground-based GNSS receivers, newly planned radars and airglow instruments greatly extend the observation coverages. In the space segment, a number of upcoming new satellite missions with capabilities of airglow, neutral winds and electron density observations will provide a variety of observation worldwide. With the large amount and diversity of datasets, sophisticated theoretical and empirical models can be validated, and implemented for inclusion of new thermosphere and ionosphere phenomena. Additionally, advances in applications of data assimilation technique on the ionosphere monitoring and forecast system are developing in progress. These recent advances in observations and models are important to move forward the status of the ionospheric space weather monitoring and forecast. It is the purpose of this session to solicit studies providing observations, theoretical and empirical modeling and data assimilation on the multiple scales of ionosphere structures, from global morphology to small scale irregularities and traveling ionospheric disturbances. Studies on magnetically quiescent and disturbed conditions will both be addressed.
