BackForward Variable: Ionospheric Total Electron Content (TEC)

Definition
Full name Ionospheric Total Electron Content (TEC)
Definition Number of electrons between two points. 
Measuring Units TECU = 1016 electrons·m-2 Uncertainty Units TECU
Horizontal Res Units km Vertical Res Units
Stability Units TECU (Stability /decade)

 

Comment: Derived from GNSS receivers from satellite and from ground. Important parameter to calibrate GNSS positioning systems. Observations at multiple viewing angles may be used to generate profiles by tomography. Zenith TEC is a desired derived quanitity.
