Understanding Inter-Hemispheric Traveling Ionospheric Disturbances and Their Mechanisms

open access: yesRemote Sensing, 2020
Traveling ionospheric disturbances (TIDs) are wave-like disturbances in ionospheric plasma density. They are often observed during both quiet (medium-scale TID) and geomagnetically disturbed (large-scale TID) conditions. Their amplitudes can reach double-

Impacts of Thunderstorm-Generated Gravity Waves on the Ionosphere-Thermosphere Using TIEGCM-NG/MAGIC Simulations and Comparisons With GNSS TEC, ICON, and COSMIC-2 Observations. [PDF]

open access: yesJ Geophys Res Space Phys
Abstract We use the TIEGCM‐NG nudged by MAGIC gravity waves to study the impacts of a severe thunderstorm system, with a hundred tornado touchdowns, on the ionospheric and thermospheric disturbances. The generated waves induce a distinct concentric ring pattern on GNSS TIDs with horizontal scales of 150–400 km and phase speeds of 150–300 m/s, which is ...

A decade of the Super Dual Auroral Radar Network (SuperDARN): scientific achievements, new techniques and future directions [PDF]

open access: yes, 2007
The Super Dual Auroral Radar Network (SuperDARN) has been operating as an international co-operative organisation for over 10 years. The network has now grown so that the fields of view of its 18 radars cover the majority of the northern and southern ...
