The Schumann Resonances – electromagnetic frequencies in the Earth-ionosphere cavity – demonstrate potential interactions ... But Schumann Resonances do fall within the 5-60 Hz frequency range.

Abstract: This work proposes a novel design of a Transformer architecture model for ionospheric total electron content (TEC) forecasting called Ionformer. This model is conceptually derived from the ...

FARR is able to model the complex interaction of electromagnetic waves with multi-scale ionospheric irregularities, capturing the effects of scintillation caused by both refractive and diffractive ...

We start discussing the measurements of mechanical parameters and variations of geochemical fluids detected before earthquakes; then we review thermal and atmospheric oscillations; finally, ...
