Description
The interplanetary particle radiation environment is primarily characterized by cosmic rays and solar energetic particle events. Recently, a novel specification solar particle radiation model was developed with the aim to expand upon the ESA Solar Accumulated and Peak Proton and Heavy Ion Radiation Environment (SAPPHIRE) model. The SAPPHIRE-2S model uses the SEPEM Reference Dataset (RDS) and the SEPEM Reference Event List (REL) which were developed primarily for implementation in the SAPPHIRE model. In the frame of the FIRESPELL project, and in order to continue the development of the SAPPHIRE-2S model, we have utilised a number of interplanetary particle datasets to include SEP electron radiation, an important component of SEP events which has not been extensively modelled, as well as low energy protons and helium (approximately in the 0.04-5 MeV energy range). These particles at these energies are relevant to radiation effects and mission specification and in this work we present the data and appropriate pre-processing methods (despiking, cross-calibration, etc.) employed. The final product is a homogeneous dataset for the new electron and low-energy ion component of SEP radiation covering all SEP events defined in the REL spanning the years 1974-2017.
This work has received funding from the European Space Agency under the "Particle Radiation Modelling for Interplanetary Missions Extending to Low Energies (FIRESPELL)" activity under ESA Contract No 4000142510/23/NL/CRS.
