| Abstract: | We systematically introduced the COSMIC ionospheric electron density inverseon technology theories and methods,and verified its reliability.Then,using COSMIC data,we calculated and analyzed 5-days’seismic ionospheric electron density distribution over the seismic area,which happened on March 11,2011 in north-east Japan.From the research we have done,we have got significant phenomenon on seismo-ionospheric anomalies and confirm the truth of feasibility on this field. |
