WebThe ionosphere is composed of layers of ionised material that behaves like a plasma between altitudes of 100–1 000 km. Ionospheric structure and activity vary based on many factors such as Earth’s location, time, altitude, solar cycle, and in recent years the structure has been vigorously studied (e.g. Davies 1990 ). WebIonospheric disturbances are a short-term deviation from regular climatology (such as diurnal variations). These disturbances can be local, regional, and sometimes global. A large category of these disturbances has characteristic wave properties in propagation and periodicity and is specifically termed as traveling ionospheric disturbances (TIDs).
