Comparison of seasonal and longitudinal variation of daytime MSTID activity using GPS observation and GAIA simulations
Sivakandan, Mani; Otsuka, Yuichi; Ghosh, Priyanka; Shinagawa, Hiroyuki; Shinbori, Atsuki; Miyoshi, Yasunobu (Earth, Planets and Space, 2021-02-04)The total electron content (TEC) data derived from the GAIA (Ground-to-topside model of Atmosphere Ionosphere for Aeronomy) is used to study the seasonal and longitudinal variation of occurrence of medium-scale traveling ... -
L‐Band Synthetic Aperture Radar Observation of Ionospheric Density Irregularities at Equatorial Plasma Depletion Region
Sato, Hiroatsu; Kim, Jun Su; Otsuka, Yuichi; Wrasse, Cristiano Max; Rodrigues de Paula, Eurico; Rodrigues de Souza, Jonas (Geophysical Research Letters, 2021-08-23)Plasma density irregularities in the equatorial ionosphere are thought to cause the distortions of L‐band Synthetic Aperture Radar (SAR) images, which have been observed in recent years, but the origin of the image distortion ...
