CEDAR email: Call for Abstracts – AGU25 Session SA023: Whole-Atmosphere Coupling and ITM Responses to Terrestrial and Space Weather Forcing

[Gasperini, Federico (Orion)]

Dear Colleagues,

We invite you to submit an abstract to the 2025 AGU Fall Meeting Session: SA023 - Whole-Atmosphere Coupling and Ionosphere-Thermosphere-Magnetosphere Responses to Terrestrial and Space Weather Forcing. The meeting will be held in New Orleans, LA, December 15-19, 2025, in a hybrid format.

Session Details:
Session Title: SA023 - Whole-Atmosphere Coupling and Ionosphere-Thermosphere-Magnetosphere Responses to Terrestrial and Space Weather Forcing
Section: SPA-Aeronomy
Session Link: https://agu.confex.com/agu/agu25/prelim.cgi/Session/247350
Primary Convener: Federico Gasperini, Orion Space Solutions
Conveners: Xian Lu, Clemson University; Shantanab Debchoudhury, Embry-Riddle Aeronautical University; Xueling Shi, Virginia Polytechnic Institute and State University; Haonan Wu, National Center for Atmospheric Research

Session Description: The Ionosphere-Thermosphere-Magnetosphere (ITM) system responds dynamically to both terrestrial weather from below and space weather from above. This session explores the relative roles and interactions of atmospheric waves—such as tides, planetary waves, and gravity waves—and external drivers, including solar irradiance, solar wind, and geomagnetic activity, in shaping global ITM variability. Special emphasis is placed on disturbances from sudden stratospheric warmings, volcanic eruptions, tropospheric convection, and geomagnetic storms. We invite observational, theoretical, and modeling studies that investigate coupling across spatial and temporal scales, with contributions from satellite missions (e.g., ICON, GOLD, AWE, COSMIC-2, MMS), ground-based networks (e.g., SuperDARN, GNSS, ISR, Fabry-Perot interferometers, magnetometer arrays), and advanced models (e.g., WACCM-X, MAGE, TIEGCM, SAMI3). This session encourages cross-disciplinary collaboration to improve understanding of whole-atmosphere coupling and its impact on space weather, electrodynamics, and thermospheric structure.

We look forward to your contribution to our AGU25 session. Please note that the abstract submission deadline is Wednesday, 30 July 2025 at 23:59 EDT/03:59 UTC.

Sincerely,
Federico Gasperini, Xian Lu, Shantanab Debchoudhury, Xueling Shi, Haonan Wu
