Abstract: In order to better monitor the seismic ionospheric disturbance and extract the anomaly information, a seismic ionospheric disturbance monitoring system was developed based on the space ionospheric environment tomograph, which include a small area monitoring network and software system. It could output two-dimension total electron content (TEC), the maximum electron density (N_mF₂) and the corresponding peak height of the F2 layer (h_mF₂) distribution map with a spatial resolution of 1°×1°. When the ionospheric disturbance exceeds 10%, alarm will be presented. The seismic ionospheric disturbance monitoring system has realized the application demonstration of space ionospheric environment tomograph in the field of seismic ionospheric monitoring. It also provides the technical basis for its further promoted application.
