摘要
将观测站实测数据的月中值按世界时进行排列,分析得到了电离层参数与太阳活动性指数F12之间的相关系数,然后,根据F12的预测数据,可以预测得到观测站的电离层参数。之后,通过Kriging地理插值法可以预测得到一定区域内观测站以外任一地点的电离层参数。上述过程形成了一个完整的区域电离层参数长期预测方法。
Arranging month median values of observed data at every site by UTC, the correlation coefficients between ionosphere parameters and the sun activity index F12 are regressed. Then according to the predicted F12, the ionosphere parameters at the observation stations can be predicted. Afterwards,using the Kriging geographical interpolation method, the ionosphere parameters at any place can be predicted in this area near China. Then the complete ionosphere parameters long-term prediction method is formed by all the above steps.
