Abstract

The near real-time global plasma bubble map is constructed by utilizing the FORMOSAT-7/COSMIC-2(F7/C2) radio occultation(RO) scintillation observations in low latitudes. Several tools investigating plasma bubbles like the rate of TEC index(ROTI), Range-TimeIntensity(RTI) diagrams of the Jicamarca Unattended Long-term Investigations of the Ionosphere and Atmosphere(JULIA), and the Global-scale Observations of the Limb and Disk(GOLD) 135.6nm airglow observations are provided validating the RO scintillations. Result shows that the F7/C2 scintillation is sensitive detecting plasma irregularities, especially for the bottom side of these bubbles, which can be used to investigating nighttime vertical plasma drifts in low latitudinal Fregion. The hourly quick look of the low latitude plasma bubble occurrence and vertical ion drift around the globe is significant to the space weather monitoring.
用FORMOSAT-7/COSMIC-2近实时监测等离子体不规则性
利用FORMOSAT-7/COSMIC-2(F7/C2)射电掩星(RO)在低纬度地区的闪烁观测,构建了近实时的全球等离子体气泡图。提供了几种研究等离子体气泡的工具,如TEC指数速率(ROTI)、Jicamarca无人值机电离层和大气长期调查(JULIA)的距离-时间-强度(RTI)图以及全球尺度的翼盘观测(GOLD) 135.6nm气辉观测(RO)。结果表明,F7/C2闪烁对等离子体不规则性的探测非常敏感,特别是对气泡底部的探测,可用于研究低纬f区的夜间垂直等离子体漂移。每小时快速观测低纬度等离子体气泡的发生和全球垂直离子漂移对空间气象监测具有重要意义。
