<p class="MsoNormal">Dear colleagues,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are cordially inviting you to participate in this year’s AGU
<b>SA018</b> session on ionospheric irregularities and scintillation. We are again encouraging early career and student participants who want to present their work in the oral session. Please consider submitting your abstract by the submission deadline, July
31, 2024. <o:p></o:p></p>

<p class="MsoNormal"><u>Session description:<o:p></o:p></u></p>
<p class="MsoNormal">Ionospheric irregularities are the main source of radio wave scintillation, rapid random fluctuations in the amplitude and phase of radio signals that adversely affect transionospheric communication and navigation systems, such as Global
Navigation Satellite Systems (GNSS), VLF and HF communications and Over the Horizon Radars (OTHR). The generation mechanisms producing these ionospheric density irregularities are controlled by the background density, electric fields, plasma drift, neutral
winds and particle precipitation. Understanding the state of the system controlling the instability onset, turbulence development and saturation is paramount for the forecasting and mitigation strategies. In this session, we invite both modeling and remote
and in situ observational studies pertinent to advancing our understanding of the role of various mechanisms and processes for the generation of ionosphere irregularities and their propagation impacts including scintillation, bending, and range delays.<o:p></o:p></p>
