Description
Solar Energetic Particle (SEP) events are some of the most hazardous phenomena of space weather, since they contain populations of ionizing radiation and as such they can present dangers for the increasingly complex electronics on board spacecraft. Recently, the list of SEP models has been expanded, thanks to ESA-driven activities that led to the creation of a reference dataset for the study of SEPs with the SEPEM reference data set. Despite this progress, the European Cooperation for Space Standardization (ECSS) still has no way to extend modelling down to lower energy particles, which are able to reach spacecraft with very high fluences impacting solar arrays and eroding surface materials. Furthermore, the modelling of the interplanetary electron environment, which contributes to charging effects and can also contribute to sensor interference, has seen little effort in the past years. In this work, we present the steps towards the creation of the RDS-low database, which has been built in the frame of FIRESPELL project, utilising a number of interplanetary particle datasets to include SEP electron radiation, as well as low energy protons and helium, spanning approximately the 0.04-5 MeV energy range. This long-term, curated and calibrated database can be invaluable to current and future modelling efforts concerning space climate.
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.
