Total Electron Content PCA-NN Prediction Model for South-European Middle Latitudes
Atmosphere, 2023 A regression-based model was previously developed to forecast total electron content (TEC) at middle latitudes. We present a more sophisticated model using neural networks (NN) instead of linear regression.

Matter content in AGN jets: constraint from cocoon dynamics? [PDF]
, 2005 The matter content of jets in active galactic nuclei is examined in a new way. We model the dynamical expansion of its cocoon embedded in the intra-cluster medium (ICM).

Spatiotemporal Prediction of Ionospheric Total Electron Content Based on ED-ConvLSTM
Remote Sensing, 2023 Total electron content (TEC) is a vital parameter for describing the state of the ionosphere, and precise prediction of TEC is of great significance for improving the accuracy of the Global Navigation Satellite System (GNSS).

Geometric total electron content models for topside ionospheric sounding [PDF]
, 2014 The ionosphere is commonly divided into the portion below (bottomside) and above (topside) the region at which peak values of electron density occur. Topside ionospheric modeling is a challenging problem because of the limited data available. Indeed, the

Storm-Time Relative Total Electron Content Modelling Using Machine Learning Techniques
Remote Sensing, 2022 Accurately predicting total electron content (TEC) during geomagnetic storms is still a challenging task for ionospheric models. In this work, a neural-network (NN)-based model is proposed which predicts relative TEC with respect to the preceding 27-day ...

Geometric quality term for station-based total electron content estimation
Annals of Geophysics, 2016 Global ionospheric maps (GIMs) are still commonly used to represent total electron content (TEC). However, a large number of permanent GPS receivers provide significant data for monitoring ionosphere.
