A Hybrid Deep Learning‐Based Forecasting Model for the Peak Height of Ionospheric F2 Layer
Space Weather, Volume 21, Issue 10, October 2023., 2023 Abstract To achieve accurate forecasting of the peak height of the ionospheric F2 layer (hmF2), we propose a hybrid deep learning model of improved seagull optimization algorithm (ISOA) optimized long short‐term memory (LSTM) model based on a complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) theory.

Influence of Lightning on the Observation of Seismic Electromagnetic Wave Anomalies
Terrestrial, Atmospheric and Oceanic Sciences, 2007 For two decades, many researchers have been claiming that pre-seismic electromagnetic phenomena may be useful in short-term earthquake prediction. Despite much effort, however, the relationship between anomalous electromagnetic signals and earthquakes ...
