The ionosphere is a key driver of space weather impacts on communication, navigation, and remote sensing systems. This session invites contributions that explore the synergy between LEO-based techniques (e.g., GNSS radio occultation and reflectometry) and ground-based GNSS observations for improved ionospheric monitoring and space weather mitigation. We seek interdisciplinary abstracts on topics such as global and regional TEC/scintillation mapping, multi-instrument data assimilation, AI-based forecasting, and the study of ionospheric structures like plasma bubbles and polar cap patches. Emphasis is placed on real-time products and applications in data-sparse regions, including the Arctic and equatorial zones. Researchers from space physics, GNSS technology, data science, and operational space weather services are encouraged to submit. This session aims to advance next-generation ionospheric models by integrating LEO and ground-based observations.
