CEDAR email: [Call for Abstracts] AOGS 2025: ST25 (Upper atmosphere disturbances driven by natural events in the solar terrestrial environment)

[Chi-Yen Lin]

Dear Colleagues,
 
The AOGS 22nd Annual Meeting (AOGS2025) will take place from July 27 to August 1, 2025, at Marina Bay Sands in Singapore. We would like to bring your attention to session ST25: Upper Atmosphere Disturbances Driven by Natural Events in the Solar Terrestrial Environment, which will emphasize all aspects of upper atmosphere disturbances caused by natural events, including seismic activity, tsunamis, volcanic eruptions, hurricanes, solar eclipses, and geomagnetic storms in the solar terrestrial environment.
 
Session Scope
Earth’s upper atmosphere, including the ionized component, ionosphere, is sensitive to upward propagated disturbances from the lower altitudes.  These disturbances could be in atmospheric acoustic and gravity waves (AGWs), large-scale planetary waves, or tides. They can be generated by lithosphere activities and lower atmosphere disturbances, such as seismic, tsunami, volcano eruptions, hurricanes, tornados, and meteorological disturbances. Another source of the disturbances comes from solar-terrestrial events, such as solar eclipses or magnetic storms. Solar eclipse could produce various disturbances from the lower atmosphere to the thermosphere, resulting in complex upper atmosphere responses. Magnetic storms could also drive global atmospheric and thermospheric disturbances through the input of energy from electromagnetic and energetical precipitations. These disturbances interact with the upper atmosphere through various complex processes and thus provide opportunities for a better understanding of the vertical coupling and teleconnection in the whole atmosphere. This session's objective is to solicit discussions on the upper atmospheric disturbances in both neutral and ionized components resulting from the disturbances of these natural events in the solar terrestrial environments. The latest results from the recent extreme geomagnetic storm events have also been solicited.

Please note that the deadline for abstract submission is February 18, 2025. We would appreciate your attendance at the meeting and your contribution to the community.
 
Sincerely,
