Ionospheric anomalies
WebThe current study also aims to provide an investigation of ionospheric anomalies associated to EQs. In order to study possible pre-and post-seismic perturbations during the preparation phase of large-magnitude EQs, statistical and machine learning algorithms are applied to Total Electron Content (TEC) from the Global Positioning System (GPS) and … Webionospheric space weather products and services that are capable of satisfying the ever-growing demand for space-based technology, and are ready for the society of the not-so-distant future.
