Revelations in the Study of Geospace Variability

Explore the latest revelations in geospace variability research in this 47-minute AGU Fall Meeting lecture. Delve into the complex interactions between the Earth's atmosphere and the solar-terrestrial system, focusing on the impact of lower atmospheric drivers on thermosphere-ionosphere variations. Discover how atmospheric tides, excited by solar radiation absorption and tropical cloud formation, propagate upward to influence geospace conditions. Examine the challenges in understanding these coupled systems, including the effects of meteorological disturbances and long-term atmospheric evolution. Trace the development of our knowledge regarding thermosphere-ionosphere variability drivers and identify unresolved questions in geospace research. Gain insights into the intricate relationship between lower atmospheric phenomena and quiescent space weather conditions, as well as their role in geospace responses to solar geomagnetic disturbances.
