Predicting and understanding the energetic particle dynamics using Cluster observations 


Elena Kronberg 
Univ. of Munich 
The terrestrial magnetosphere is an efficient plasma accelerator. Energetic particles affect space observations and the space weather. I will present the results of observations of energetic charged particles (~>40 keV-~1 MeV) by the Cluster/Research with Adaptive Particle Imaging Detectors (RAPID). Originally, investigating the dynamics of the radiation belts was not a scientific objective of RAPID. With a newly developed technique to clean the electron data from contamination, it is possible to use long-term observational data in the radiation belts. Protons at energies of 100 keV can enter X-Ray telescopes and produce erroneous signals, leading to a loss of astrophysical observations. I present a model for predicting the proton intensities in the near-Earth space based on machine learning. I will discuss the model performance using multi-satellite observations of a substorm.
