Multi-dimensional Analyses of the First Measurement from the Low Frequency (LF) Radio Waves Receiving Station at Ariel University, Israel

The use of very low frequency (VLF) radio waves for monitoring the lower part of ionosphere (D region) has contributed immensely to explore this unique domain as satellites and other ground-based instrumentations have not been able to physically assess and characterized it. Several deployed ground- and space-based observational techniques not only enhance a robust capability to monitor, model and predict processes in the atmosphere-ionosphere-magnetosphere coupled regions, but also act as key feature to perform scientific studies in geo-sciences related areas. Here, we present preliminary results from multi-dimensional analyses of LF broadband measurement conducted from Ariel University (AU), Israel, as a complementary useful data source to other available ground- and space- based observational tools, already deployed. The AU LF (0.50 – 470 kHz) observational site, receives electromagnetic waves from different worldwide VLF transmitters as well as other natural sources such as lightning discharges. The station data is mainly used for diagnostic probing of ionospheric irregularities, caused by space weather events such as gamma-ray burst and EUV radiation, along with additional atmospheric electricity measurements. Additionally, different Machine Learning (ML) are used to study spheric waveforms in order to infer their exact location along with different physical characteristics.
