The ionosphere is an area approximately 60 km above the surface of the Earth where the plasma density is sufficiently high to affect communications. Hence, the distribution of plasma in the ionosphere is one of the important indicators of space weather, and it is particularly important to monitor the ionosphere and predict space weather effects.
The parameters of the ionospheric F2 peak electron density (NmF2), F2 peak height (HmF2), and the S4 amplitude scintillation index are used to understand ionospheric structure, disturbances, and the effect of ionospheric irregularities on satellite navigation and communications. The analysis of their daily, seasonal, and geographical latitude variations is important for understanding ionospheric space weather effects. In this study, the data from FORMOSAT-7/COSMIC-2 (F7/C2) and FORMOSAT-5/Advanced Ionospheric Probe (F5/AIP) are used as the main data, and the analysis examining observations from the two missions are prepared for subsequent discussion.
The correlation between the distribution of the NmF2, HmF2, S4 index and the vertical plasma velocity can be further understood by comparing the co-located observation points of F7/C2 and F5/AIP, which are located close to each other and have a small difference in observation time. This will allow for the relation between scintillation, ionospheric irregularities, and vertical ionospheric structure to be examined in detail.
