  • Owing to the sparse data, the reconstructing ionospheric maps are not accurate enough by using the interpolation methods directly, especially in the verges. In order to obtain better TEC maps, the reconstruction was performed by Inverse Distance Weighting and Kriging Methods with IRI-2007 used as the background field. The test produced a better performance according to using Cross-validation method. As a result, the new technique decreased the errors effectively, especially in the verges, and the proportions of absolute errors between -0.25~0.25 TECU at all grid points in the reconstructing ionospheric map were improved by 70\% and 100\%. Meanwhile statistic errors showed a normal distribution. The reconstructed precision can be improved by using more exact background or successive correction method.
