In this study, for the first time, we quantitatively investigate the posteclipse response of the global ionosphere and thermosphere system to the recent Great American Solar Eclipse using a high-resolution, global, coupled ionosphere-thermosphere-electrodynamics model. It was found that the posteclipse response of the ionosphere and thermosphere is significant and worldwide, which was not expected. Specifically, even 9hr after the eclipse ended, the globally averaged ionospheric total electron content perturbations were about 0.2 total electron content unit, and the corresponding changes in neutral temperature and winds reached 2K and 2m/s. The changes in the global dynamic and energetic processes associated with the solar eclipse contributed to this long-lasting response of the ionosphere and thermosphere during the posteclipse period.
