Abstract
We present procedure of ionospheric disturbance spatial structure reconstruction. The procedure is based on the imaging of ionospheric Total Electron Content (TEC) increments distribution. The TEC value is measured using data from Japanese GPS Earth Observation Network (GEONET) which includes more than 1000 two-frequency ground-based GPS receivers. To reconstruct disturbance spatial structure we selected the TEC increment values and corresponding geographic coordinates of the ionospheric point for the specified time moment. The obtained data is spline-approximated on equal stationary reference grid. To test presented procedure we reconstructed spatial structure of ionospheric disturbance, specially simulated for conditions of September 25, 2003, Hokkaido strong earthquake. The results of testing showed, that the presented procedure provides reconstruction of disturbance spatial structure and its dynamics with high time resolution.
