Statistical analysis of ionospheric total electron content (TEC): long-term estimation of extreme TEC in Japan [PDF]
Ionospheric total electron content (TEC) is one of the key parameters for users of radio-based systems, such as the Global Navigation Satellite System, high-frequency communication systems, and space-based remote sensing systems, since total ionospheric ...

Isolated ionospheric disturbances as deduced from global GPS network [PDF]
We investigate an unusual class of medium-scale traveling ionospheric disturbances of the nonwave type, isolated ionospheric disturbances (IIDs) that manifest themselves in total electron content (TEC) variations in the form of single aperiodic ...

Prediction of Global Ionospheric Total Electron Content (TEC) Based on SAM‐ConvLSTM Model
This paper first applies a prediction model based on self‐attention memory ConvLSTM (SAM‐ConvLSTM) to predict the global ionospheric total electron content (TEC) maps with up to 1 day of lead time.

Ionospheric total electron content (TEC) above Ecuador
Abstract The equatorial ionosphere over the Ecuadorian territory has not been previously studied, although there are some studies in other equatorial geographical positions, local research is required to characterize the ionospheric magnetoactive plasma in this region.
