L-Time average of longterm EPT proton and electron observations

Dataset used in: "Atmospheric loss of energetic electrons and protons from the radiation belts after the exceptional injection of the 11 May 2024 superstorm leading to four electron belts".

The Energetic Particle Telescope (EPT) measures the flux of energetic electrons and protons in the Earth's radiation belts on a low Earth orbit (820 km) onboard the PROBA-V satellite.

This dataset is comprised in its entirety of processed data from the EPT. In each file, the data is averaged in time and in McIlwain L-parameter (L-Time bins). However, the binning, the type of particles fluxes, and time coverage differs between the files.

  • Electrons weekly 2020-2025 LT This file contains the electron fluxes averaged in L-Time bins with a weekly resolution, covering data spanning from 2020 to 2025

  • Electrons daily 2024-2025 LT This file contains the electron fluxes averaged in L-Time bins with a daily resolution, covering data spanning from 2024 to 2025

  • Protons daily 2024-2025 LT This file contains the proton fluxes averaged in L-Time bins with a daily resolution in the southern hemisphere, covering data spanning from 2024 to 2025

Note: The detailed structure of each file is given in the file description.
