Junhai Li and Shuanggen Jin

Data sets

A new version of the NeQuick ionosphere electron density model (http://t-ict4d.ictp.it/nequick2/source-code) B. Nava, P. Coïsson, and S. M. Radicella https://doi.org/10.1016/j.jastp.2008.01.015

Short summary

In this paper, we discuss the higher-order ionospheric effects on electron density estimation. We estimate the higher-order ionospheric effect carefully and obtain some conclusions. The results show that the second-order ionospheric effects cannot be ignored in precise ionospheric electron density estimation. The azimuth, the solar activity, and the occultation time and position are the main effect factors of the high-order ionospheric delay which we should consider.
