Near‐Real‐Time Identification of the Source of Ionospheric Disturbances
Journal of Geophysical Research: Space Physics, Volume 129, Issue 11, November 2024.Abstract The ionosphere is characterized by a large number of disturbances generated in response to a wide range of phenomena, including natural hazards, space weather and man‐made events. Identification of the origin of ionospheric disturbances (ID), especially in real or near‐real‐time (NRT), is an extremely difficult task, and it is one of the most ...
