CEDAR email: EGU Session ST3.6: Thermospheric variability and coupling dynamics due to sources above and below

[Billett, Daniel]

Dear CEDAR community,


Abstraction submission is open for EGU 2024, and we would like to draw your attention to our session on Ionosphere/Thermosphere coupling and variability.


Session information, including abstract submission, can be found at https://meetingorganizer.copernicus.org/EGU24/session/49740. The deadline for abstracts is 10 January 2024.


Looking forward to seeing you in Vienna!


Best regards,

Daniel Billett,  Elisabetta Iorfida, David Themens, Magnus Ivarsen

ST3.6: Thermospheric variability and coupling dynamics due to sources above and below

https://meetingorganizer.copernicus.org/EGU24/session/49740


Abstract: As a boundary region between Earth’s dense atmosphere and space, the thermosphere experiences a vast range of forcing from both terrestrial and space-borne sources. Geomagnetic storms and coupling to the magnetosphere deposits energy via the ionosphere and heats the thermosphere, drastically changing its composition and launching atmospheric waves which propagate globally. Meteorological activity, atmospheric instabilities and energetic lithospheric events can generate intense gravity waves which propagate upwards, manifesting in the ionosphere/thermosphere as TIDs/TADs. These mechanisms can then interact which each other, resulting in a vast and variable region of mingling dynamics that can impact both satellite and communication technologies. The dynamics which characterize this region can be measured and derived by different type of sources, such as satellites flying at different altitudes or ground-based observatories.


This session solicits presentations that highlight and study the variability of the thermosphere system, including its density, temperature, winds, structure, and coupling to the ionosphere, from forcing sources located both above and below this region.
