摘　　要：通过对比特大磁暴时CHAMP卫星探测的质量密度和NRLMSIS00模式,在400 km高度上的数据,阐述了特大磁暴时大气密度扰动的一些规律。结果表明:NRLMSIS00模式在特大磁暴时低估了地磁扰动对大气密度变化的影响,不能很好地反映出实际热层大气密度变化。By contrast the data of mass density between NRLMSIS00＇s and CHAMP satellite＇s at 400 km altitude at the time of geomagnetic super storms, the characters of the send. The results show that the NRLMSIS00 underestimates th atmospheric density. In other words, the NRLMSIS00 can not sphere at the time of geomagnetic super storms. atmospheric mass density of the thermosphere is pree impact of geomagnetic disturbance on the change of accurately reflect atmospheric density of the thermosphere at the time of geomagnetic super storms.
