Variations of the thermosphere in response to geomagnetic forcing: Our current understanding and some future plans [presentation]
This presentation uses both models and observations to summarize thermospheric variability, particularly as it pertains to geomagnetic storms. The ability to analyze both the data and models simultaneously has given us a greater understanding of the physical processes that lead to these observed cha...

Text conference material 2008 ftncar 2023-09-04T18:33:13Z This presentation uses both models and observations to summarize thermospheric variability, particularly as it pertains to geomagnetic storms. The ability to analyze both the data and models simultaneously has given us a greater understanding of the physical processes that lead to these observed changes. These forcing mechanisms are also briefly described here. As well as these storm-time issues, there are significant discrepancies even in quiet times. One example of such a discrepancy is the anomaly in electron densities that occurs over the South Pacific and Antarctica in the southern summer -- the Weddell Sea anomaly. Efforts are in progress to help us past these bottle necks so that we can understand the causes of all of the variability that is seen in the thermosphere. One example of such work is the NASA GOLD mission, which is briefly described here. GOLD will image thermospheric temperatures and composition from geosynchronous orbit permitting us to obtain a greater understanding of how the simultaneous temporal and spatial changes in these fields are related.
