Tsunami detection by GPS-derived ionospheric total electron content [PDF]
Scientific Reports, 2021 To unravel the relationship between earthquake and tsunami using ionospheric total electron content (TEC) changes, we analyzed two Chilean tsunamigenic subduction earthquakes: the 2014 Pisagua Mw 8.1 and the 2015 Illapel Mw 8.3.

Deep learning of total electron content [PDF]
SN Applied Sciences, 2021 One of the most notable errors in the global navigation satellite system (GNSS) is the ionospheric delay due to the total electron content (TEC). TEC is the number of electrons in the ionosphere in the signal path from the satellite to the receiver ...

Localized total electron content enhancements in the Southern Hemisphere [PDF]
Annales Geophysicae, 2020 This paper is dedicated to the investigation of localized TEC (total electron content) enhancements (LTEs), which were detected in the Southern Hemisphere via the analysis of global ionospheric maps. Using data from different years (2014, 2015 and 2018),

Temporal-Spatial Variation of Global GPS-Derived Total Electron Content, 1999-2013. [PDF]
PLoS ONE, 2015 To investigate the temporal-spatial distribution and evolutions of global Total Electron Content (TEC), we estimate the global TEC data from 1999 to 2013 by processing the GPS data collected by the International Global Navigation Satellite System (GNSS ...

Global Distribution of Persistence of Total Electron Content Anomaly [PDF]
Atmosphere, 2019 To better understand the ionospheric morphology response to lithospheric activities, we study the global location preference of the positive and negative total electron content (TEC) anomalies persisting continuously for longer than 24 h at middle and ...

Slant total electron content for Sirio-Mortelliccio ray path
Annals of Geophysics, 2006 The Total Electron Content (TEC) is used to indicate the ionisation of the ionosphere. TEC is a quantity that concern for predicting space weather effects on telecommunications, improving the accuracy of satellite navigation, fly control vehicles and ...

Total Electron Content during Auroral Conditions.
, 1987 Coordinated spectrophotometric and ionospheric electron content measurements were conducted during a variety of auroral conditions at Churchill, Manitoba for a total of 14 clear nights in November and December, 1984. Ground based narrow angle filter photometers measured the temporal history of 4278 and 6300 A emissions for a {dollar}2\sp\circ{dollar ...

Total electron content variations over the earthquakes epicenters
Physical Sciences and Technology, 2015 In this work the total electron content variations over the strongest earthquakes epicenters for the period 1999-2014 was investigated. In order to provide good accuracy of local total electron content estimation the picenters in the territory with ...
