| Abstract: | In this paper, the changes of proton's fluxes for a certain posihon in the low altitude are caiculatal using IGRF magnetic field models with epoch from l945 to l990 and the latest trapped radiation model AP8MAX, and the effects of magnetic field's long-term changes on L, B /B0 are discussed.The correct methods to calculate L, B /B0 and the correct usage of trapped radiation belt models together with IGRF magnetic field models are recommended and discussed. |
