A Combined Neural Network‐ and Physics‐Based Approach for Modeling Plasmasphere Dynamics
(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 ... -
Identifying Radiation Belt Electron Source and Loss Processes by Assimilating Spacecraft Data in a Three-Dimensional Diffusion Model
(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 ... -
Quantifying the Effects of EMIC Wave Scattering and Magnetopause Shadowing in the Outer Electron Radiation Belt by Means of Data Assimilation
(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 ... -
Resource Model Updating For Compositional Geometallurgical Variables
(Mathematical Geosciences, 2020-08-13)In the field of mineral resources extraction, one main challenge is to meet production targets in terms of geometallurgical properties. These properties influence the processing of the ore and are often represented in ... -
The Kalmag model as a candidate for IGRF-13
(Earth, Planets and Space, 2020-10-29)We present a new model of the geomagnetic field spanning the last 20 years and called Kalmag. Deriving from the assimilation of CHAMP and Swarm vector field measurements, it separates the different contributions to the ...
