A CORRECTED METHOD OF THE INTERNATIONAL REFERENCE IONOSPHERE TO BE USED IN GHINESE REGION

A corrected method of the International Reference Ionosphere(CRI) is proposed when it is used in Chinese region, based on the long-term observations of the Chinese ionosonde stations.The method of predicting the ionospheric F layer in the Asia Oceania Region is adopted in calculation of f0F2 and M(3000)F2 instead of CCIR/URSI Coefficients,a more reasonable description of the Occurrence of F1 layer and a greater E peak height are used In the CRI.After various comparisons with measured data, it is shown that the CRI gives more accurate values than the IRI does when they are used in Chinese region.
