BackForward Variable: Solar wind velocity

Definition
Full name Solar wind velocity
Definition Vector velocity of solar wind plasma
Measuring Units km·s-1 Uncertainty Units %
Horizontal Res Units Vertical Res Units
Stability Units % (Stability /decade)

 

Comment: Typically measured at the L1 Lagrange point, but also valuable at other locations such as the L5 Lagrange point. Derived from measurements of electron and ion fluxes in the low-energy solar wind range (electrons: 1 to 1240 eV; ions: 0.26 to 35 keV). Vital for forecasts and warnings of geomagnetic storms.
