Web12 apr. 2024 · Ionospheric effective height (IEH), a key factor affecting ionospheric modeling accuracies by dominating mapping errors, is defined as the single-layer height. From previous studies, the fixed IEH model for a global or local area is unreasonable with respect to the dynamic ionosphere. We present a flexible IEH solution based on neural … WebThe ionosphere is the ionized part of the upper layer of the earth's atmosphere. The air molecules there are ionized by solar radiation. This layer of the atmosphere is a fairly good conductor, and radio waves are often "bounced" off the bottom of the ionosphere back toward the earth, in a process called skip or skywave propagation.

WebA DAPS’ strong electric field can significantly modify magnetosphere-ionosphere convection and energetic particle drift and heat the ionosphere and thermosphere. This project aims to determine fundamental DAPS properties and their impacts, including how DAPS vary under different conditions, what contributes to these variations, and their role …
WebGlobal Navigation Satellite System (GNSS)-based ionospheric anomalies are nowadays used to identify a possible earthquake (EQ) precursor and hence a new research topic in seismic studies. The current study also aims to provide an investigation of ionospheric anomalies associated to EQs. WebAbstract. One important contribution to the magnetic field measured at satellite altitude and at ground level comes from the external currents. We used the total field data sampled …
Web10 apr. 2024 · These electrical currents are part of the spectacular auroras that attract millions of tourists to the poles every year. They are just a small portion of a vast current running between Earth and its magnetosphere but can have major negative effects on society, including electrical grids and technology in space.
