Ionospheric plasma irregularities studied with Swarm satellites
E3S Web of Conferences, 2018 To study and characterise the ionospheric plasma irregularities at all latitudes, one can employ in-situ measurements by satellites in polar orbits, such as the European Space Agency’s Swarm mission.

Beyond the Electrostatic Approach: Numerical Simulations of Martian Ionospheric Irregularities
AGU AdvancesNumerical simulations play an essential role in the study of ionospheric irregularities. In the past few decades, electrostatic simulations have successfully simulated the nonlinear evolution of terrestrial ionospheric irregularities.

A decade of the Super Dual Auroral Radar Network (SuperDARN) : scientific achievements, new techniques and future directions [PDF]
, 2007 The Super Dual Auroral Radar Network (SuperDARN) has been operating as an international co-operative organization 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 ...

Journal of Nepal Physical Society, 2021 The low-latitude ionosphere is characterized by large-scale instabilities in the post-sunset hours due to the distinct geometry of the earth’s magnetic field lines at the equator. The magnetic field lines are horizontal at the equator contributing to the high vertical drift velocity of the plasma bubbles growing from the bottomside of the ionospheric F-

Diffusion spreading of middle-latitude ionospheric plasma irregularities [PDF]
Annales Geophysicae, 1995 In contrast to the way that the spreading of irregularities in a plasma is usually considered, the diffusion spreading of irregularities stretched along the geomagnetic field B is examined using a three-dimensional rigorous numerical model of quasi ...

Comparison between SuperDARN flow vectors and equivalent ionospheric currents from ground magnetometer arrays [PDF]
, 2012 Equivalent ionospheric currents obtained with the spherical elementary current systems (SECS) method and derived from nearly 100 ground magnetometers spread over North America and Greenland are compared with ionospheric flow vectors measured by the ...
