Özet
The polar ionosphere is a highly dynamic natural plasma affected by many parameters such as space weather, solar activity, hours, and latitude. In this study, the dependence of the Solar zenith angle on the ionospheric peak electron height measured by the JB57N URSI coded ionosonde in Antarctica was determined between 21 December 2019 to 21 March 2020, which corresponds to the summer season in the Southern hemisphere. Examining the effect of solar radiation, which is the main cause of ionization in the ionosphere, in the Antarctic regions, which have been understudied compared to the Arctic regions, is very important in order to better understand the global ionosphere-magnetosphere system, considering the ability of particles accelerated to larger energies due to the concentration of magnetic field lines in the Polar regions to penetrate the ionosphere.
Since the examined times naturally coincide with the longest daytime periods in the region, the effect of solar radiation, which is the main reason for the ionization of the ionosphere, could be more easily examined. In the study, it was observed that for the changing Solar Zenith Angle, hmF2 increased as the angle increased towards the end of the examined date and as expected.
