    Abstract
  • The Ionospheric Total Electron Content (TEC) is one of the most important parameters in ionospheric sounding. A large number of vertical TEC data can be obtained by using the hundreds of GPS stations which are distributed around the world. In this paper, a reconstruction method of high precision TEC is proposed， and the Kriging interpolation method is used to interpolate the vertical TEC data in order to obtain the high resolution two-dimensional distribution of TEC. The accuracy and effectiveness of the proposed method are compared with the measured data. Based on the two-dimensional distribution, the changes of regional TEC value with time and latitude are analyzed, particularly in the influence of geomagnetic storms on the TEC value. and The differences and explanations of TEC changes in different latitudes are also given. The related research results can provide the method support for the establishment of regional high resolution ionospheric monitoring system.
