This dataset contains the list of radiation belts electron enhancement events identified using the ground-based index Ca with the method described in the following article:
Bernoux, G., Nguyen, G., Sicard, A., & Maget, M. (2025). Automatic Identification of Past Radiation Belts Electron Enhancement Events Using a Ground-Based Parameter. Earth and Space Science, 12, e2024EA003945. https://doi.org/10.1029/2024EA003945
These are radiation belts electron enhancement events events corresponding to medium-energy (0.03 ≲ E ≲ 1 MeV) electrons located at the core of the outer electron belt from 1868 to 2021 (inclusive).
The list is in a CSV table with one header, 4243 data rows and 6 columns:
id: the event’s relative identifier;
start date: event start date and time;
end date: event end date and time;
max date: date and time of maximum Ca of the event;
max value: event’s maximum Ca value (nT);
category: probable cause of the event, which can take six values: empty cell, “icme”, “sir”, “multiple icmes”, “multiple sirs”, “sir and icme”.
Date and times are in ISO 8601 format. We may update the list occasionally in the
future, for example when new definitive values of the aa index are published.
The research leading to these results has received funding from the European Union's Horizon Europe research and innovation programme under grant agreement No 101081772 (FARBES project).
