太阳质子事件对太阳同步轨道空间辐射环境影响分析

THE EFFECT ANALYSIS OF SOLAR PROTON EVENT ON SPACE RADIATION ENVIRONMENT AT SOLAR SYNCHRONOUS ORBIT

介绍了南大西洋异常区的辐射环境及其特点，重点研究了发生于２０００年７月１４日的太阳质子事件对太阳同步轨道空间环境造成的影响．太阳质子事件期间，抵达近地空间的高能电子、质子及重离子对太阳同步轨道空间环境造成剧烈地扰动，并且不同种类不同能量的拄子扰动特征不尽相同．

According to detected results of Space Particle Composition Detector on board the FY-1C meteorology satellite, the paper presents radiation environmot and its distribution characteristics in the South Atlatic Anomalous during quiet days without solar proton events and magnetostorms. The effect analysis of solar proton event on July 14, 2000 on solar synchronous orbit space radiation environment has been discussed in detail. Space environment near Earth was disturbed intensively during the solar proton event. High energy electrons, protons and heavy ious possess high flux over both polar regions. The distributions of disturbances for different particles over both polar regions are different.
