First Observation of Ionospheric Plasma Bubble Signatures by Ca+ Lidar at Low Latitude
Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.Abstract Ionospheric plasma bubbles refer to density depletion structures in the ionosphere, which are usually seen in the electron density profiles observed by radar, and have never been observed in the density profiles of metallic ions. In this letter, we report the first observation of plasma bubble signatures captured by lidar, manifested as ...
