The session purpose is to provide an opportunity for presentations and discussions on the Earth’s ionosphere and its close (i.e. atmosphere and magnetosphere) and far (i.e. lithosphere and plasmasphere) physical environments. Specific attention is given to the whistler mode waves allowing efficient diagnostic tools for remote sensing and studying the ionized plasma in the ionosphere. We welcome observations recorded by ground-based network (e.g. AWDANet, AWESOME, INFREP, SAVNET, SEGMA) and space-borne satellites (e.g. CHAMP, CSES, DEMETER, GRACE, SWARM). We invite both theoretical and observational contributions on the physical processes in the ionosphere, particularly those associated to wave-particle interactions and related to space weather impact. The session also extends to the study of disturbances of the electrical circuit between the lithosphere and the ionosphere induced by flashes of lightning and the seismic activity.
