Total electron content at low latitudes

open access: yesJournal of Earth System Science, 1978
Radio beacon from ATS-6 at 140 MHz was used to measure the changes in the polarization angle (Faraday rotation) at Bombay, Rajkot, Ahmedabad, Udaipur and Patiala during October 1975 to July 1976. In this paper, results of diurnal, seasonal and latitudinal variations in total electron content (TEC) derived from these measurements are reported.

Evolutionary Prediction of Total Electron Content over Cyprus [PDF]

open access: yes, 2010
Total Electron Content (TEC) is an ionospheric characteristic used to derive the signal delay imposed by the ionosphere on trans-ionospheric links and subsequently overwhelm its negative impact in accurate position determination. In this paper, an Evolutionary Algorithm (EA), and particularly a Genetic Programming (GP) based model is designed.

Total Electron Content PCA-NN Prediction Model for South-European Middle Latitudes

open access: yesAtmosphere, 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.

Spatiotemporal Prediction of Ionospheric Total Electron Content Based on ED-ConvLSTM

open access: yesRemote 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).

Total Electron Content Studies of the Ionosphere

open access: yes, 1973
Abstract : Radio waves that pass through the earth's ionosphere travel more slowly than their free space velocity due to the group path delay of the ionosphere. This group path delay, directly proportional to the total electron content of the ionosphere, can be an important source of error to VHF, UHF and L-band satellite detection radars and satellite

IONORING: Real-Time Monitoring of the Total Electron Content over Italy

open access: yesRemote Sensing, 2021
IONORING (IONOspheric RING) is a tool capable to provide the real-time monitoring and modeling of the ionospheric Total Electron Content (TEC) over Italy, in the latitudinal and longitudinal ranges of 35°N–48°N and 5°E–20°E, respectively.
