Session: QV - Earth's Magnetosphere and Radiation Belts


The Van Allen radiation belts contain ultra-relativistic electrons, with energies covering a range from several keVs to several MeVs. Many of the physical processes occurring in these particle populations are not fully understood due to their high time-space variability, specially during magnetospheric storms. It is crucial to understand these physical processes and their effects on technologies and human activities in space. 

The purpose of this work is to show the first steps into developing a new tool to provide alerts upon particle storms happening in the Radiation Belts. A characterization of the electron population in the outer radiation belt, for energies ranging from 1.6 to 18.9 MeV, was done. The measurements analysed were made by the Relativistic Electron-Proton Telescope (REPT) instrument on-board the Van Allen probes, launched into orbit in August 2012 and deactivated by the end of 2019.

A proto-operative product was developed using GOES-15 data. Different thresholds were defined to link different levels of radiation storms. Finally, in order to provide this information in a user-friendly way, an automated plot is refreshed and uploaded every 5 minutes to the LAMP's website (Laboratorio Argentino de Meteorología del esPacio), which is integrated into the weekly reports done by LAMP.
