中国地区电离层f_oF_2的重构方法研究

A study on the reconstruction of f_oF_2 in China region

提出了一种以中国参考电离层为背景的中国地区电离层foF2的区域重构方法,该方法根据foF2时间和空间相关性,将foF2的估计值与中国参考电离层模型值之差的相对值作为区域变化参量,引入电离层距离、经度因子和纬度因子等参数实现了电离层区域重构.利用我国电离层foF2的数据,对该方法的重构精度进行了评估,实现了中国地区的电离层区域预报.

By using the Kriging method which is based on China Reference ionosphere(CRI),the method for reconstruction of ionospheric foF2in China region is proposed. In this method the regional variant is adopted as the relative difference between the estimated and the CRI modeled values of foF2.Considering the temporal and spatial pertinence of the ionosphere foF2,the ionospheric distance,latitude factor and longitude factor are introduced and the Kriging method is proposed for the reconstruction of ionospheric foF2in China region.The estimation of the reconstruction accuracy is done by using the ionospheric sounding data in China region and the simulations of the ionospheric reconstruction,which practices the ionospheric reconstruction in China region.
