BackForward Variable: Ionospheric Scintillation

Definition
Full name Ionospheric Scintillation
Definition Random fluctuations of radio waves resulting of small scale variations of the ionospheric electron density in space and time.
Measuring Units dimensionless Uncertainty Units %
Horizontal Res Units km Vertical Res Units
Stability Units % (Stability /decade)

 

Comment: Characterized by two indices: (S4) is the coefficient of variation of intensity [standard deviation divided by mean] and (Sigma Phi) is the standard deviation of the phase of the radio signal. Typically observed in GPS signals operating at 1.58 and 1.23 GHz and relevant for all transionospheric transmissions.
