Magnetosphere Ionosphere Coupling: A Comprehensive Guide To Space Physics And Chemistry Magnetosphere Ionosphere Coupling (Physics And Chemistry In Space 23)

The boundary between Earth's magnetic field and the charged particles in the surrounding space, known as the magnetosphere, forms a dynamic and interactive region with the ionosphere, the Earth's upper atmosphere. This region is known as the magnetosphere-ionosphere coupling region. Plasma, charged particles flowing in a gaseous state, forms the interface between these two domains, facilitating the exchange of mass, energy, and momentum, giving rise to a complex array of geophysical phenomena.
