Medium-Scale Traveling Ionospheric Disturbances and Plasma Bubbles Observed by an All-Sky Airglow Imager at Yonaguni, Japan

Terrestrial, Atmospheric and Oceanic Sciences, 2009
We report on night time air glow imaging observations of the low latitude ionosphere by means of a 630-m all-sky imager in stalled in March 2006 at Yonaguni, Japan (24.5°N, 123.0°E; 14.6°N geomagnetic), about 100 km east of Taiwan.

Comparison of electron densities and temperatures on satellite in situ measurements and ground remote ob servations

, 2019
© 2019 IEEE. To determine the degree of connectivity of the electron density disturbance of the MSTID type below and above the F layer peak, a comparison data of the ionosonde and the low-orbit constellation of the Swarm satellites was made. It was found

Multi-instrument analysis of medium-scale travelling ionospheric disturbances generated by an intense tropospheric jet-front system with severe convection in Europe in August 2023

Journal of Space Weather and Space Climate
Tropospheric jet-front systems and intense convection are known to be potential sources of atmospheric gravity waves (AGWs), which can propagate upward.
