  • The evaluation of the radiation belt AP9 model is not systematic enough. The high, medium and low solar activity level is classified in view of the F10.7 index. The corresponding data of the proton flux between 140 and 500MeV observed by NOAA-15 are chosen as the reference data. The objective region is the South Atlantic Anomaly (SAA) region. The evaluation criteria conclude the goodness of boundary fitness and the magnitude difference between model and observation. By contrasting with the current applied AP8 model and reference data under high, medium and low solar activity level, the new radiation belts proton model AP9 is systematically and quantitatively evaluated. The results show that both the AP8 and AP9 model can reconstruct the SAA region. However, the outline of SAA region reconstructed by AP8 is more consistent with the observation than that of AP9. On the whole, the AP8 and AP9 results are higher than the observations, and AP8 results are closer to the observations than AP9 results. The lower the solar activity level is, the smaller the difference between AP9 model results and observations is.
