Traveling Ionospheric Disturbances Driven from Above and from Below
Session ID#: 160364
Session Description:
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.
