BackForward Variable: Electron differential directional flux

Definition
Full name Electron differential directional flux
Definition Flux density energy spectrum of low-, medium-, and high-energy electrons from the magnetosphere, the radiation belts or the interplanetary medium, per unit solid angle
Measuring Units electrons·(cm2 s sr eV)-1 Uncertainty Units %
Horizontal Res Units degrees Vertical Res Units
Stability Units % (Stability /decade)

 

Comment: A measure of plasma and the radiation environment that could present a hazard to satellites and humans in space. Low energy refers to 0 eV to 50 keV. Medium energy refers to 50 keV to 100s of keV. High energy refers to 100s of keV up to a few MeV and above. The horizontal resolution is counted in degrees of arc along an Earth orbit, i.e. 90 degrees correspond to 4 measurement points The horizontal resolution is counted in degrees of arc along an Earth orbit, i.e. 90 degrees correspond to 4 measurement points.
