| Abstract: |
| The AP9/AE9/SPM radiation environment model is systematically studied. The development history, modeling data, model capability, application methods, model characteristics, model limitations and development trend of AP9/AE9/SPM radiation environment model are mainly introduced. The characteristics, data coverage time range and energy range of the 11 released versions in the AP9/AE9/SPM radiation environment model “spiral” development pathway are summarized. During the development process, it is pointed out that the AP9/AE9/SPM radiation environment model is constantly integrated with the latest data and theoretical knowledge to achieve the purpose of extending the model energy coverage and increasing the spatial particle distribution. The newly released AP9/AE9/SPM radiation environment model can be used in both command-line applications and graphical user interface applications, covering the complete radiation belt, basically covering the energy range of electrons and protons. However, the latest version of AP9/AE9/SPM still has some limitations, which will be gradually improved with the accumulation of radiation belt detection data and the further cognition of the mechanism of radiation belts. The research in this paper can help users quickly understand and correctly use the AP9/AE9/SPM model, and provide an important reference for the research and development of the independent radiation belt model in China. |
