<span id="ms-rterangepaste-start"></span><span style="color:rgb(38,38,38); font-family:Roboto,sans-serif; font-size:14px">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, tropical cyclones, thunderstorms, etc.), earthquakes, tsunamis, volcanic eruptions, explosions, and spacecraft launches. TIDs generated from different types of sources may exhibit similar or very different characteristics in their spatial and temporal
 scales, periodicities, propagation speeds and directions. Meanwhile, TIDs generated from the same type of sources may exhibit different characteristics depending on the local ionospheric conditions. Therefore, 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.</span><span id="ms-rterangepaste-end"></span>
