海南地区电离层等离子体泡的多仪器同时观测

Ionospheric plasma bubbles simultaneously observed by multi-instruments in Hainan region

摘要: 根据海南电离层观测站测高仪、闪烁监测仪和中华一号卫星的观测数据，对2004年4月23日三种仪器同时观测到的电离层等离子体泡事件进行了分析.测高仪从14∶30 UT到17∶45 UT观测到了强区域型扩展F现象，闪烁监测仪观测到闪烁现象出现的时间范围略大于强区域型扩展F的时间范围.在16∶33—16∶34 UT期间卫星在海南上空观测到了两个等离子体泡现象.经分析认为，强区域扩展F和闪烁现象都是由卫星观测到的等离子体泡所引起的，从而给出了测高仪、闪烁监测仪和卫星同时观测到等离子体泡的重要观测证据.

Abstract: Based on data observed by ionosonde and scintillation monitor at Hainan station，as well as ROCSAT-1 satellite，the ionospheric plasma bubbles which simultaneously observed by the three instruments in Hainan region on April 23，2004，have been analyzed.The Strong range Spread F（SSF)observed by ionosonde started at 14∶30 UT and ended at 17∶45 UT.The occurrence time range of ionospheric scintillations observed by scintillation monitor was larger than that of SSF.From 16∶33 UT to 16∶34 UT，ROCSAT-1 detected two bubbles above Hainan region.The SSF and scintillations are considered to be caused by the bubbles.Thus we presented the significant evidence of bubbles simultaneously observed by ionosonde，scintillation monitor，and satellite.
