Description

Spacecraft design has consistently relied on specification models to provide estimates of radiation exposure ranges to develop the necessary passive protections. As they mainly rely on in-situ data, the current standard models can suffer from data gaps and bias. Fortunately, climate reanalysis offers a viable alternative, enabling the construction of continuous and reliable cartographies of the radiation belt dynamics over extended periods. This is achieved through the assimilation of historical observations with theoretical radiation belt models. In this presentation, we will delve into the climate reanalysis operation of trapped electrons and protons over the last decade, using the Salammbô code and conducted within the framework of the GLORAB project.

This work received funding from the European Space Agency under ESA Contract 4000137689/22/NL/CRS.
