Dear Colleagues,
<div class=""><br class="">
</div>
<div class="">We would like to bring to your attention the following AGU session co-organized by SPA-Aeronomy and Geodesy:</div>
<div class=""><br class="">
</div>
<div class=""><b class="">Session Title: </b></div>
<div class="">Traveling Ionospheric Disturbances Driven from Above and from Below</div>
<div class=""><br class="">
</div>
<div class=""><b class="">Session Description:</b></div>
<div class="">This session will focus on the identification and source differentiation of traveling ionospheric disturbances (TIDs), which are frequently observed in the ionosphere at all latitudes and longitudes. TIDs can be driven from above by solar and
magnetospheric disturbances, or driven from below by lower atmospheric and surface forcing, including but not limited to tropospheric weather events (hurricanes, tornadoes, thunderstorms, and tropical cyclones), earthquakes, tsunamis, volcanic eruptions, explosions,
and spacecraft launches. TIDs generated from different types of sources may exhibit similar or different characteristics in their spatial and temporal scales, periodicities, propagation speeds and directions. It remains a challenge to distinguish TIDs from
different types of sources in ionospheric observations. We solicit theoretical, observational, and modeling contributions on better understanding of the origins, generation mechanisms, and characteristics of TIDs. In particular, we welcome innovative approaches to
identify and differentiate TIDs generated from various sources.</div>
