Analysis of the ionospheric anomaly at Great Wall Station, Antarctica
In this paper, we use an empirical method to derive the height of maximum electron concentration of the F2 region and the effective meridional neutral wind at Great Wall Station, Antarctica. The meridional wind is also calculated with the HWM-90 model. Results can be used to explain two anomaly feat...
