Plasmaspheric hiss refers to a type of low-frequency electromagnetic wave observed in the Earth's plasmasphere, which is a region of cold plasma located above the ionosphere. These hiss waves are generated by interactions between energetic electrons and electromagnetic fields, playing a crucial role in the dynamics of space weather and the overall behavior of the magnetosphere. Understanding plasmaspheric hiss helps to reveal how wave-particle interactions can affect satellite operations and communication systems in space.
