全球电离层模型的构建是描述地球近地空间环境的重要环节。IGS提供了全球电离层图GIMs,其时间和空间的分辨率较低。研究了BERN程序代码的GIMs插值方法和格网插值算法,对比了最邻近插值、三次样条插值和双线性插值不同插值算法间的差异。程序实现了全天任意时刻全球电离层模型的三维动态演示功能。为全球电离层分布变化研究提供了动态交互的三维电离层模型,为全球电离层模型的构建和电离层形态学研究提供了一种更为逼真、可交互的电离层三维演示平台。
The construction of the global ionosphere model is an important part of describing the Earth’s near-Earth environment. IGS provides global ionosphere GIMs with low temporal and spatial resolution. The GERN interpolation method and the grid interpolation algorithm of BERN program code are studied. The differences between the interpolation methods of the nearest neighbor interpolation, the cubic spline interpolation and the bilinear interpolation different interpolation algorithms are compared. The program implements the 3D dynamic demonstration of the global ionospheric model at any time of the day. Provides a dynamic and interactive three-dimensional ionospheric model for the study of global ionospheric distribution changes, and provides a more realistic and interactive ionospheric three-dimensional demonstration platform for global ionospheric model construction and ionospheric morphology.
