Ionospheric Effects Analysis Associated with aTotal Solar Eclipse on July 22,2009

    Abstract
  • When a total solar eclipse occurs,various radiation sources from the sun will be coveredgradually by the moon,thus resulting in all kinds of geophysics phenomenon.Therefore,to carry outobservation and investigation on the geophysical effects related to total solar eclipse is of certain prac-tical significance and scientific value.Based on the Ionosonde data before and after a total solar eclipseon July 22,2009,this article analyzes the ionospheric response during this period,and attempts to ex-plore the ionospheric effect caused by total solar eclipse by the inversion of ionospheric GNSS occulta-tion.Results demonstrate that the remarkable change of the ionosphere caused by total solar eclipsecan be detected by both plumb meter and COSMIC occultation inversion methods,although the tem-poral resolution of the ionospheric effect extracted by COSMIC occultation inversion needs further im-provement.
