Abstract

Computerized ionospheric tomography(CIT) is suitable for monitoring large-scale spatial structures and disturbances of ionospheric electron density.Combined of GPS TEC from single site and observations from another ionosonde,The MART algorithm to calculate the vertical distribution of the ionospheric electron density over the site with IRI model is presented in this paper.CIT is performed with actual observations from daytime and nighttime.The results indicate the reliability of this method.
