Empirically Estimated Electron Lifetimes in the Earth's Radiation Belts: Van Allen Probe Observations

Abstract We use measurements from NASA's Van Allen Probes to calculate the decay time constants for electrons over a wide range of energies (30 keV to 4 MeV) and L values ( L = 1.3–6.0) in the Earth's radiation belts. Using an automated routine to identify flux decay events, we construct a...
