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∶30UT到17∶45UT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∶34UT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.Based on data observed by ionosonde and scintillation monitor at Hainan station,as well as ROCSAT-1satellite,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∶30UT and ended at 17∶45UT.The occurrence time range of ionospheric scintillations observed by scintillation monitor was larger than that of SSF.From 16∶33UT to 16∶34UT,ROCSAT-1detected 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.
