| 1 | Newly established autonomous adaptive low-power instrument platform(AAL-PIP) chain on East Antarctic Plateau and operation显示文摘An autonomous adaptive low-power instrument platform(AAL-PIP)chain of six stations has been newly established on East Antarctic Plateau along the 40°geomagnetic meridian,to investigate interhemispheric geomagnetically conjugate current systems,waves,and other space weather phenomena in Polar Regions.These six stations,PG0 to PG5,which host low-power magnetometers(Fluxgate and Searchcoil),dual frequency GPS receivers,HF radio experiment,and run autonomously with solar power and two-way satellite communication,are designated at the geomagnetically conjugate(based on the International Geomagnetic Reference Field)locations of the West Greenland geomagnetic chain covering magnetic latitudes from 70°to 80°.We present the development,deployment,and operation of this chain,as well as the data collected by the chain and some preliminary scientific results showing evidence of interhemispheric asymmetries,which are important to better understand Solar Wind–Magnetosphere–Ionosphere(SWMI)coupling in Polar Regions.Recent investigations focus on magnetic impulse(MI)events,traveling convection vortices(TCVs),and ultra-low frequency(ULF)waves in the coupled southern and northern hemispheres. | Zhonghua XU Michael DHARTINGER Robert CLAUER Daniel WEIMER Kshitija DESHPANDE Hyomin KIM Stephen MUSKO Anna WILLER Thomas EDWARDS Shane COYLE Yuxiang PENG Dong LIN John BOWMAN | 2019 | Advances in Polar Science2019，30，4： | 0 |
| 2 | 基于小波分析的地磁甚低频脉动指数及其在高磁纬度地区甚低频脉动共轭对比研究中的应用显示文摘地磁甚低频脉动是甚低频磁流体波在磁层中传播的地面表现,开发近实时空间天气产品来监测这些地磁脉动至关重要。本文基于小波分析提出一种地磁甚低频脉动指数,并将其应用于研究在南极洲及西格陵兰岛的磁共轭位置观测到的地磁甚低频脉动。研究结果表明,(1)该指数可有效识别Pc4—Pc5频率范围内的脉动事件(包括瞬态事件),并获得甚低频脉动在时域和频域的重要特征。(2)基于共轭位置地磁脉动的小波分析比较揭示了冬至日、夏至日条件下南北半球甚低频脉动的相似性和差异。本研究也表明,南北半球磁共轭位置观测到地磁脉动存在的差异受到行星际磁场条件、磁场拓扑、观测磁纬度和日照等条件影响,需要进一步研究案例中实际磁层和电离层配置以及驱动条件。 | 徐中华 CRobert Clauer Michael DHartinger Hyomin Kim Daniel R Weimer | 2024 | 极地研究2024，36，1： | 0 |
