Generation of Quasi‐Periodic Dayside Medium Scale Traveling Ionospheric Disturbances (MSTIDs) by Intermittent Lobe Reconnection

Geophysical Research Letters
The medium‐scale traveling ionospheric disturbances (MSTIDs) can be excited by many sources. Among those magnetic reconnection has been proposed as a potential driver for dayside MSTIDs, but direct evidence has been limited. Using ground‐based radar data

High-latitude MSTIDs over the EISCAT-3D site: solar activity and seasonal dependency

Annales Geophysicae
This work involves an investigation of high-latitude medium scale traveling ionospheric disturbances (MSTIDs) over the newly established EISCAT-3D radar site. We have used the ground backscatter data from an HF radar located at Hankasalmi, Finland (∼62.3° N, ∼26.61° E geographic coordinates), which is a part of the SuperDARN (Super

Interhemispheric Comparison of the MSTID Response to Sudden Stratospheric Warmings Observed by SuperDARN Radars

Medium Scale Traveling Ionospheric Disturbances (MSTIDs) are periodic perturbations in the ionosphere that can impact radio wave propagation. They can be observed using a variety of techniques including the Super Dual Auoral Radar Network (Super-DARN ...

Correlation of Rate of TEC Index and Spread F over European Ionosondes

Atmosphere
One of the most popular indices for monitoring the occurrence and intensity of ionospheric L-band irregularities is the Rate of TEC Index (ROTI). Due to low TEC in the mid-latitude ionosphere, ROTI has received significantly less attention than the ...

Investigation into the earliest generation of medium-scale traveling ionospheric disturbances with electrodynamic signatures using dense GNSS observations over Japan

Earth, Planets and Space
Understanding the earliest formation stages of medium-scale traveling ionospheric disturbances (MSTIDs) with electrodynamic signatures (commonly referred to as nighttime MSTIDs) is essential for comprehending their full development.
