TOTAL ELECTRON CONTENT
DÉFINITION
- Total Electron Content (TEC) is the number of free electrons in a column of the Earth's ionosphere. TEC is affected by geomagnetic storms and measurements of TEC is crucial for calibrating measurements obtained by active radar and altimeter instruments such as used on TOPEX/Poseidon. Measurements of TEC are a by-product if sea surface height measurements and TEC global ionosphere climatologies have been developed from TOPEX/Poseidon measurements.
