Ionospheric foF2 reconstruction and its application to the short-term forecasting in China region
中国地区电离层foF2重构方法及其在短期预报中的应用

The CRI based Kriging method has been proposed for reconstruction of ionospheric f_oF_2 in China region. In this method the regional variate is adopted as the relative difference between the estimated and the CRI modeled values of f_oF_2. Introducing the ionospheric distance the regional ionospheric reconstruction can be realized by using the Kriging method. The CRI based Kriging method would improve the accuracy and stability in the regional ionospheric reconstruction as compared with the straight f_oF_2 reconstruction. Based on the systematic measurements of the Chinese Ionosounde Network computer simulations of the ionospheric reconstruction have been done for different solar activity years, months and hours, which give the estimates of the reconstruction accuracy in China region. This method, combined with the autocorrelation method for single station, will practise the short-term forecasting of f_oF_2 in China region.
