On the Extraordinary L‐Band Scintillation Event Observed in the American Sector During the 23–24 March 2023 Geomagnetic Storm

Space Weather
We report an extraordinary L‐band scintillation event detected in the American sector on the night of 23–24 March 2023. The event was detected using observations distributed from the magnetic equator to mid latitudes.

Analyzing Scintillation Using Ionospheric Asymmetry Index

, 2014
Existence of random electron-density fluctuations cause scintillation of radio waves on trans-ionospheric links. Ionospheric irregularities that account for scintillation may vary significantly in spatial range and drift with the background plasma at ...

Prediction of Ionospheric Scintillations Using Machine Learning Techniques during Solar Cycle 24 across the Equatorial Anomaly

Atmosphere
Ionospheric scintillation is a pressing issue in space weather studies due to its diverse effects on positioning, navigation, and timing (PNT) systems. Developing an accurate and timely prediction model for this event is crucial.

Ionospheric Scintillation Forecasting Using Machine Learning

IGARSS 2024 - 2024 IEEE International Geoscience and Remote Sensing Symposium
This study explores the use of historical data from Global Navigation Satellite System (GNSS) scintillation monitoring receivers to predict the severity of amplitude scintillation, a phenomenon where electron density irregularities in the ionosphere cause fluctuations in GNSS signal power. These fluctuations can be measured using the S4 index, but real-

Implementation of Machine Learning Methods for Ionospheric Scintillation Data Analysis

, 2020
The ionosphere is a region in the Earth’s upper atmosphere, where atoms are ionized due to solar radiation. The behavior of the ionosphere depends on time and location, and it is highly influenced by solar activity.
