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 ...

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 ...

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 ...
