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 ... -
Beating 1 Sievert: Optimal Radiation Shielding of Astronauts on a Mission to Mars
Space radiation is one of the main concerns in planning long‐term human space missions. There are two main types of hazardous radiation: solar energetic particles (SEP) and galactic cosmic rays (GCR). The intensity and ... -
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.; Effenberger, F. (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 ...
