from dynamical processes in the ionosphere including transport processes,
instabilities, and turbulence, being driven and modulated by Space Weather
phenomena and by the forcing from the neutral atmosphere. Ionospheric
irregularities affect the propagation of radio waves (e.g., scintillation),
posing a threat on modern radio systems. Among these, Global Navigation
Satellite Systems (GNSS) critical applications, for which accuracy,
availability, continuity, and integrity are mandatory, and HF/VHF/UHF radio
communications that exploit reflection and refraction by the ionosphere. The
session welcomes papers addressing recent developments in definition,
implementation, standardization, modeling and predictability of ionospheric
perturbation indices and activity scales. The session is also willing to ease
the dialog with the user community (e.g., aviation, farming, safety of life) by
accepting contributions addressing how the use of indices and scale can support
specific operations and services. Papers addressing data standardization,
preservation and access are also welcome.</span></p></div><font color="#888888"><div><br><br></div></font></div></div></div>
