BackForward Variable: Ionospheric plasma velocity

Full name Ionospheric plasma velocity
Definition Velocity of bulk plasma or electrons (depending on measurement technique) as a function of altitude in the ionosphere.
Measuring Units km·s-1 Uncertainty Units km·s-1
Horizontal Res Units km Vertical Res Units
Stability Units km·s-1 (Stability /decade)


Comment: Line of sight velocity is used to derive plasma convection velocity and electric field.
