Spatial and temporal mapping of the Martian radiative environment

Atmospheric Radiation Model for Ionizing Spectra (ARAMIS) is a newly built Martian surface radiative environment model, which allows getting the surface flux spectra of different secondary particle anywhere on Mars. ARAMIS simulations are based on GEANT4, a toolkit simulating the passage of particle through matter. This thesis describes how the location-dependent regolith composition has been retrieved over the whole Martian surface and implemented within ARAMIS’ framework.
