Satellite System (GNSS) has become a ubiquitous tool for global ionospheric
monitoring. GNSS measurements have enabled both global and regional studies of
ionospheric Total Electron Content (TEC), ionospheric scintillation, and
travelling ionospheric disturbances (TIDs), and have aided recent advances in
ionospheric specification and forecast modeling efforts. This session solicits
papers on ionospheric measurements and monitoring using GNSS techniques. Papers
related to new measurements of ionospheric TEC and scintillations, TIDs, and
advances in GNSS-based ionospheric monitoring are appropriate for this session.
Modeling and theory related to GNSS measurements of the ionosphere, and their
interpretation are also welcomed.<font class="Apple-style-span"><o:p></o:p></font></font></span></p><p class="MsoNormal"><span style="color: rgb(31, 42, 51); "><font class="Apple-style-span" face="Arial" size="4"><br></font></span></p><p class="MsoNormal"><font class="Apple-style-span" face="Arial" size="4">The abstract submission deadline is Tuesday, August 6.</font></p><p class="MsoNormal"><font class="Apple-style-span" color="#1f2a33" face="Arial" size="4">We look forward to seeing you in San Francisco!</font></p><p class="MsoNormal"><font class="Apple-style-span" color="#1f2a33" face="Arial" size="4">Best Wishes!</font></p><div><font class="Apple-style-span" face="Arial" size="4"><br></font></div><div><font class="Apple-style-span" face="Arial" size="4">Conveners:</font></div><div><font class="Apple-style-span" face="Arial" size="4">Geoff Crowley (ASTRA)</font></div><div><font class="Apple-style-span" face="Arial" size="4">Charlie Carrano (Boston College)</font></div><div><font class="Apple-style-span" face="Arial" size="4">Rebecca Bishop (The Aerospace Corp.)</font></div><div><font class="Apple-style-span" face="Arial" size="4">Susan Skone (University of Calgary)</font></div><div><br></div>
