This session addresses the dynamics of ionospheric irregularities and their influence on radio wave propagation, particularly scintillation. These irregularities represent fluctuations in plasma density compared to background values and span a wide range of scales, from centimeters to hundreds of kilometers. Their formation results from a complex interplay of ionospheric dynamical processes, including electrodynamical phenomena, transport processes, instabilities, and turbulence, which are driven and influenced by Space Weather events and interactions with the neutral atmosphere. The implications of ionospheric irregularities are profound, presenting significant challenges to modern radio systems. This is especially critical for Global Navigation Satellite Systems (GNSS), where precision, availability, continuity, and integrity are essential. Additionally, high-frequency (HF), very high-frequency (VHF), and ultra-high-frequency (UHF) radio communications, reliant on ionospheric reflection and refraction, are susceptible to these irregularities. The session focuses on recent advancements in modelling, diagnostic measurements, and prediction/forecasting techniques to better comprehend the underlying processes governing ionospheric irregularities, their dynamic evolution, and spatial characteristics. We also encourage contributions that investigate the impact of scintillation on GNSS signals and radio communications, satellite-based communication, navigation, Synthetic Aperture Radar (SAR), and various other systems, spanning different ionospheric sectors. Furthermore, the session invites papers addressing the latest developments in defining, implementing, standardizing, modelling, and predicting ionospheric perturbation indices and activity scales.
