摘要

利用DEMETER卫星上等离子体分析仪器(IAP)探测到的离子密度,探讨FORMOSAT-5卫星上先进电离层探测器(AIP)的科学载荷能否用于观测电离层等离子体不规则的空间天气。DEMETER/IAP离子密度在±15°纬度范围内的低纬度不规则现象是夜间现象,在南美洲-中非地区几乎全年都很突出,特别是在5 - 8月。在全球范围内,DEMETER/ IAP离子密度的高纬度不规则性在纬度±65°左右出现,并在冬季和春分月/半球变得非常强烈。DEMETER/IAP结果表明,FORMOSAT-5/AIP不仅可以用于低纬度电离层,而且可以用于高纬度电离层的日间/夜间等离子体不规则空间天气监测。

An observing system simulation experiment for FORMOSAT-5/AIP probing topside ionospheric plasma irregularities by using DEMETER/IAP
The ion density probed by IAP (Instrument d'Analyse du Plasma) on board the DEMETER (Detection of ElectroMagnetic Emissions Transmitted from Earthquake Regions) satellite is used to find whether the science payload of Advanced Ionospheric Probe (AIP) on board FORMOSAT-5 can be employed to observe space weather of ionospheric plasma irregularities. The low-latitude irregularities within ±15° dip latitudes of the DEMETER/IAP ion density are nighttime phenomena, and become prominent in the South America-Central Africa sector almost all year round, especially during May to August. The high-latitude irregularities of the DEMETER/ IAP ion density appear around ±65° dip latitude worldwide in both daytime and nighttime, and become very intense in the winter and the equinox month/hemisphere. DEMETER/IAP results show that FORMOSAT-5/AIP can be used to monitor space weather of ionospheric daytime/nighttime plasma irregularities in not only the low-but also high-latitude ionosphere.
