Ionospheric disturbances in Japan detected by ALOS-2 subband azimuth offset

Earth, Planets and Space
Global Navigation Satellite Systems (GNSS) and synthetic aperture radar (SAR) are valuable tools for observing ionospheric disturbances. While GNSS provides continuous temporal data with limited spatial resolution, SAR offers high-resolution spatial ...

A study of large, medium and small scale structures in the topside ionosphere [PDF]

Alouette and ISIS data were studied for large, medium, and small scale structures in the ionosphere. Correlation was also sought with measurements by other satellites, such as the Atmosphere Explorer C and E and the Dynamic Explorer 2 satellites, of both

The correlation of VLF propagation variations with atmospheric planetary-scale waves [PDF]

Variations in the received daytime phase of long distance, cesium-controlled, VLF transmission were compared to the height variations of the 10-mb isobaric surface during the first three months of 1965 and 1969.

The Relation Between Magnetospheric State Parameters and the Occurrence of Plasma Depletion Events in the Night-Time Mid-Latitude F-Region [PDF]

, 2010
Studies using all-sky imagers have revealed the presence of various ionospheric irregularities in the night-time mid-latitude F-region. The most prevalent and well known of these are the Medium Scale Traveling Ionospheric Disturbances (MSTIDs) that ...

Three‐Dimensional Characterization of Global Ionospheric Disturbances During the 15 January 2022 Tonga Volcanic Eruption

Geophysical Research Letters
The global 3‐dimensional structure of the concentric traveling ionospheric disturbances (CTIDs) triggered by 2022 Tonga volcano was reconstructed by using the 3‐dimensional computerized ionospheric tomography (3DCIT) technique and extensive global ...
