This session addresses Strategic Thrust #1 (Encourage and Undertake a Systems Perspective to Geospace) and Strategic Thrust #4 (Develop Observational and Instrumentation Strategies for Geospace System Studies). In particular, we want to discuss future observational campaigns to better understand the origins of TIDs.
1. How the associated questions will be addressed: Through multi-instrument campaigns and the coupling of high-resolution meteorological models with ionospheric electrodynamic models.
2. What resources exist, are planned and/or are needed: Distributed ground-based networks of instrumentation (GPS, Ionosonde, Imagers) exist and are expanding. Future CubeSat missions from ISS orbit will measure in situ properties of TIDs.
3. How progress should be measured: We will identify the gaps in our measurement capabilities and provide recommendations on multi-instrument campaigns to improve understanding of the key TID generation mechanisms.
Traveling Ionospheric Disturbances are a frequent feature of the ionosphere at all latitudes. It is believed that there are a number of processes responsible for their generation including: the Perkins instability, high latitude forcing, lower atmospheric forcing resulting from severe tropospheric weather events (e.g., hurricanes, tornadoes, tropical cyclones, thunderstorms), earthquakes, tsunamis, volcanic eruptions, meteor impacts, as well as explosions, spacecraft launches, etc. This workshop will attempt to better understand the origin of TIDs and how to distinguish different types of TIDs from each other. We are interested in both modeling and data studies of TIDs. In particular, we are interested in how to use multi-instrument approaches to better understand the phenomena.
This is where the final summary workshop report will be.
