A Combined Neural Network‐ and Physics‐Based Approach for Modeling Plasmasphere Dynamics
Zhelavskaya, I. S.; Aseev, N. A.
; Shprits, Y. Y.
(Journal of Geophysical Research: Space Physics, 2021-03-16)
In recent years, feedforward neural networks (NNs) have been successfully applied to reconstruct global plasmasphere dynamics in the equatorial plane. These neural network‐based models capture the large‐scale dynamics of ... -
A Comparison of Radial Diffusion Coefficients in 1‐D and 3‐D Long‐Term Radiation Belt Simulations
Drozdov, A. Y.; Allison, H. J.
; Shprits, Y. Y.
; Elkington, S. R.
; Aseev, N. A.
(Journal of Geophysical Research: Space Physics, 2021-08-13)
Radial diffusion is one of the dominant physical mechanisms driving acceleration and loss of radiation belt electrons. A number of parameterizations for radial diffusion coefficients have been developed, each differing in ... -
Identifying Radiation Belt Electron Source and Loss Processes by Assimilating Spacecraft Data in a Three-Dimensional Diffusion Model
Cervantes, S.; Shprits, Y. Y.
; Aseev, N. A.
; Drozdov, A. Y.
; Castillo, A.; Stolle, C.
(Journal of Geophysical Research: Space Physics, 2020)
Data assimilation aims to blend incomplete and inaccurate data with physics-based dynamical models. In the Earth's radiation belts, it is used to reconstruct electron phase space density, and it has become an increasingly ... -
Medium Energy Electron Flux in Earth's Outer Radiation Belt (MERLIN): A Machine Learning Model
Smirnov, A. G.; Berrendorf, M.
; Shprits, Y. Y.
; Kronberg, E. A.
; Allison, H. J.
; Aseev, N. A.
; Zhelavskaya, I. S.
; Morley, S. K.
; Reeves, G. D.
; Carver, M. R.

(Space Weather, 2020-10-30)
The radiation belts of the Earth, filled with energetic electrons, comprise complex and dynamic systems that pose a significant threat to satellite operation. While various models of electron flux both for low and relativistic ... -
Quantifying the Effects of EMIC Wave Scattering and Magnetopause Shadowing in the Outer Electron Radiation Belt by Means of Data Assimilation
Cervantes, S.; Shprits, Y. Y.
; Aseev, N. A.
; Allison, H. J.
(Journal of Geophysical Research: Space Physics, 2020)
In this study we investigate two distinct loss mechanisms responsible for the rapid dropouts of radiation belt electrons by assimilating data from Van Allen Probes A and B and Geostationary Operational Environmental ...
