Temporal Correlation between Ionospheric Storm-Enhanced Density Plume and Plasmaspheric Plume Occurrence
Xiangning Chu, Shunrong Zhang, Jacob Bortnik +5
We present a statistical evidence of a temporal correlation between ionospheric storm-enhanced density (SED) and plasmaspheric plumes during magnetic storms. We identified SED plum…
Electron Temperature Gradients Regulate the Duration of Two-Stage Plasmasphere Refilling
Jaden Fitzpatrick, Kausik Chatterjee, Naomi Maruyama +5
After geomagnetic storms erode the plasmasphere, cold ionospheric plasma flows along magnetic field lines to refill the depleted flux tubes. Previous studies have suggested that re…
Machine Learning Interpretability of Outer Radiation Belt Enhancement \& Depletion Events
Donglai Ma, Jacob Bortnik, Qianli Ma +2
We investigate the response of outer radiation belt electron fluxes to different solar wind and geomagnetic indices using an interpretable machine learning method. We reconstruct t…
Opening the Black Box of the Radiation Belt Machine Learning Model
Donglai Ma, Jacob Bortnik, Xiangning Chu +3
Many Machine Learning (ML) systems, especially neural networks, are fundamentally regarded as black boxes since it is difficult to grasp how they function once they have been train…
Relativistic electron flux model in the outer radiation belt using a neural network approach
Xiangning Chu, Donglai Ma, Jacob Bortnik +10
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 Ele…
Modeling the dynamic variability of sub-relativistic outer radiation belt electron fluxes using machine learning
Donglai Ma, Xiangning Chu, Jacob Bortnik +6
We present a set of neural network models that reproduce the dynamics of electron fluxes in the range of 50 keV 1 MeV in the outer radiation belt. The Outer Radiation belt E…
On the generation of probabilistic forecasts from deterministic models
Enrico Camporeale, Xiangning Chu, Oleksiy Agapitov +1
Most of the methods that produce space weather forecasts are based on deterministic models. In order to generate a probabilistic forecast, a model needs to be run several times sam…
