SHELLS: Specifying High-altitude Electrons using Low-altitude LEO Systems


SHELLS is a neural network model of the current and historical electron radiation belt flux. The model was developed by using a neural network to learn the function needed to map from simultaneous low and high altitude electron flux measurements. Once that function is learned, the global flux is created by mapping measurements from the low altitude POES satellites throughout the magnetosphere.

Electron Radiation Belt Flux Plots

The plots show the electron flux (log10(#/cm2-s-str-keV) near the magnetic equator versus time (x-axis) and L-shell (y-axis). The L-shell is a magnetic coordinate that is approximately the radial distance from Earth (Re).
