Multipoint observations of Ionospheric Alfvén Resonance

Multipoint observations of Ionospheric Alfvén Resonance

Among the processes that form properties of the geospace in the circumterrestrial plasma the electromagnetic resonances of the Earth, such as Schummann Resonance (SR) and Ionospheric Alfvén Resonance (IAR) are of great importance. IAR is more localized in space than SR and its properties largely dep...
