1DEMETER卫星探测到的强震前O^+浓度变化显示文摘利用DEMETER卫星观测数据,采用level-2图像目视解译的方法和重访轨道对比方法,对2006年5月3日发生在汤加群岛的7.9级地震进行分析.从震前6天、震前2天、震前1天和震后2天的level-2图像可看到,电场和等离子体参量在震中上空偏北的位置出现扰动信号,震前的扰动信号幅度随地震时间临近有所增强,扰动持续时间也相应增加;震后2天扰动信号依然存在,其幅度并未减弱.通过对比震前1天的轨道在2006年至2008年内的重访轨道,发现O^+浓度存在三类较规律的变化特征,即在夏季时,北半球的值高于南半球;冬季时则相反;二分季节时,南北半球含量相当.本文给出了地震和磁暴对O+浓度的不同影响,地震影响最靠近震中位置轨道上的O+浓度,而磁暴影响全球轨道上O^+浓度分布.同时获取了DEMETER卫星上朗缪尔探针在上述重访轨道同步探测的电子浓度数据,发现电子浓度与O^+浓度存在同步增加.等离子体浓度增加的现象可能与地震产生异常电场进而影响电离层结构有关.欧阳新艳 张学民 申旭辉 黄建平 刘静 泽仁志玛 赵庶凡 2011空间科学学报2011,31,5:9
2The HEPD particle detector of the CSES satellite mission for investigating seismo-associated perturbations of the Van Allen belts显示文摘CSES(China Seismo-Electromagnetic Satellite) is a mission developed by CNSA(Chinese National Space Administration) and ASI(Italian Space Agency), to investigate the near-Earth electromagnetic, plasma and particle environment, for studying the seismo-associated disturbances in the ionosphere-magnetosphere transition zone. The anthropogenic and electromagnetic noise,as well as the natural non-seismic electromagnetic emissions is mainly due to tropospheric activity. In particular, the mission aims to confirming the existence of possible temporal correlations between the occurrence of earthquakes for medium and strong magnitude and the observation in space of electromagnetic perturbations, plasma variations and precipitation of bursts with highenergy charged particles from the inner Van Allen belt. In this framework, the high energy particle detector(HEPD) of the CSES mission has been developed by the Italian LIMADOU Collaboration. HEPD is an advanced detector based on a tower of scintillators and a silicon tracker that provides good energy and angular resolution and a wide angular acceptance, for electrons of 3–100 Me V, protons of 30–200 Me V and light nuclei up to the oxygen. CSES satellite has been launched on February 2^(nd), 2018 from the Jiuquan Satellite Launch Center(China).AMBROSI Giovanni BARTOCCI Simona BASARA Laurent BATTISTON Roberto BURGER William J.

3基于地震电离层现象研究结果的分析与总结显示文摘地震电离层现象作为地震事件在电离层中的物理表象,随着观测资料的积累不断地被发现和报道。大量研究结果表明,地震电离层现象复杂多样,难以捕捉和确认。本文针对主要的地震电离层现象进行简要介绍,并依据研究参量、地震事件的震级、异常出现的时间、异常的空间方位以及异常的正负等要素,对以往的地震电离层现象进行分类总结,尝试从现有研究结果中挖掘地震电离层异常出现在震前的天数与震级的关系、异常空间分布方位及频次、正负异常的震中距与震级的关系,探索地震电离层异常现象在时间上的变化特征和空间上的分布特征。何宇飞 杨冬梅 和少鹏 2020中国地震2020,36,2:4
