Inhomogeneous structure of the high-latitude ionosphere as observed at Norilsk [PDF]
, 2001 In March and August/September 1995, February 1996, and in March-April 1998, observations of the inhomogeneous structure of the high-latitude ionosphere were carried out at Norilsk (geomagnetic latitude and longitude are 64.2 N and 160.4 E, and L=5.2 ...

Preliminary results on the ionospheric structure at dawn time observed during HRIS campaigns
Annals of Geophysics, 1994 Several campaigns of ionospheric vertical soundings with short-time interval between them (HRIS) have been recently performed at the ionospheric station in Rome. Some preliminary results concerning periods around local sunrise are presented.

Traveling Ionospheric Disturbances at Mars
Geophysical Research Letters, 2019 AbstractWe report the first extraterrestrial observation of traveling ionospheric disturbances (TIDs) in the ionosphere of Mars (below ≈160 km) by NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft. TIDs are ionospheric waves manifesting as an oscillation in density, velocity, and composition of ionospheric plasma.

The synthesis of travelling ionospheric disturbance (TID) signatures in HF radar observations using ray tracing [PDF]
Annales Geophysicae, 2000 Characteristic signatures are often observed in HF radar range-time-intensity plots when travelling ionospheric disturbances (TIDs) are present. These signatures, in particular the variation of the F-region skip distance, have been synthesised using a
