We present a machine-learning-based model of relativistic electron fluxes >1.8 MeV using a neural network approach in the Earth’s outer radiation belt. The Outer RadIation belt Electron Neural net model for Relativistic electrons (ORIENT-R) uses only solar wind conditions and geomagnetic indices as input. For the first time, we show that the state of the outer radiation belt can be determined using only solar wind conditions and geomagnetic indices, without any initial and boundary conditions… Expand

Multiyear Measurements of Radiation Belt Electrons: Acceleration, Transport, and Loss
TLDR
This work portrays the radiation belt acceleration, transport, and loss characteristics over a wide range of geomagnetic events and highlights features seen repeatedly in the data (three‐belt structures, β€œimpenetrable” barrier properties, and radial diffusion signatures) in the context of acceleration and loss mechanisms.
