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 ...

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 ...

Low latitude monthly total electron content composite correlations
Journal of Space Weather and Space Climate, 2023 Spatial correlations of total electron content (TEC) variability are compared among two SAMI3 model runs and Jet Propulsion Laboratory Global Ionospheric Maps (JPL/GIM). Individual monthly correlation maps are constructed with Equatorial reference points

Total Electron Content Estimation with Reg‐Est [PDF]
Journal of Geophysical Research: Space Physics, 2007 Total Electron Content (TEC) constitutes one of the key elements for observing the variable structure of the ionosphere. GPS provides a cost‐effective alternative in TEC estimation through earth‐based receivers. In this paper, one of the TEC estimation methods, namely Reg‐Est, is investigated in detail in terms of its parameters and developed further ...

Variations of total electron content during a magnetic storm [PDF]
Geofísica Internacional, 2002 En este trabajo se analizan las variaciones del Contenido Electrónico Total (CET) durante una tormenta geomagnética, calculado a partir de mediciones del retardo ionosférico sobre las señales de código y fase, transmitidas por los satélites del Sistema ...
