The Error of Global Ionospheric Map‐TEC During Equatorial Plasma Bubble Event in the High Solar Activity Year

Space Weather
In this study, the error of total electron content (TEC) derived from the global ionospheric map (GIM) (GIM‐TEC) during equatorial plasma bubble (EPB) event is investigated for the first time.

3D tomographic analysis of equatorial plasma bubble using GNSS-TEC data from Indonesian GNSS Network [PDF]

Equatorial Plasma Bubbles (EPBs) are ionospheric irregularities that take place near the magnetic equator. EPBs most commonly occur after sunset during the equinox months, although they can also be observed during other seasons.

Auroral Effect on Mid‐Latitude Ionospheric Disturbances Over Europe During the Extreme Geomagnetic Storm of 10 May 2024

Space Weather
Large ionospheric disturbances were observed over Europe during the extreme geomagnetic storm on 10 May 2024. This study analyzes GNSS‐derived total electron content (TEC) and all‐sky imager data to investigate these disturbances.

Reliability Assessment of Multi-Source TEC Maps over Brazil Using Ground Truth Validation

Atmosphere
Total Electron Content (TEC) maps allow the evaluation of the state of the ionosphere. There are many providers/sources of worldwide or regional TEC maps for the continuous monitoring of the ionosphere, which employ different GNSS monitoring networks for

Can we detect X/M/C-class solar flares from global navigation satellite system data?

Results in Physics, 2019
Based on the total electron content (TEC) data from global navigation satellite system (GNSS), we analyzed 224 classified solar flares (SFs) occurred in 2014–2017. We suggest an algorithm for SF automatic detection.

The 27-Day Oscillation in Ionospheric Total Electron Content Observed by GNSS

Atmosphere
The 27-day oscillation in total electron content (TEC) is analysed by means of world maps of TEC. The TEC maps are derived from measurements of the ground receiver network of the Global Navigation Satellite System (GNSS) and are provided by the ...
