Abstract

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.
