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.
