“…For all stations, diurnal TEC variations exhibit clear TEC drop throughout the eclipse hours. The outcomes agree well with the investigations done by enormous researchers around the globe (Alizadeh et al., 2020; Baran et al., 2003; Panda et al., 2013), which advocates for the decrease in TEC during the eclipse hour (day of the eclipse), contrasted with other typical days. On other normal days, we anticipate a steady increment in TEC to a maximum value at peak hours of the day, which is clearly witnessed in Figure 11.…”

“…As a result of the solar eclipse, an apparent effect on the ionosphere can be witnessed. A solar eclipse occurs when the Moon passes between Earth and the Sun and its shadow falls on the Earth, thereby totally or partly obscuring the Sun for a viewer on Earth (Alizadeh et al., 2020). During a solar eclipse, the amount of the Sun's radiation reaching the earth diminishes and so we can expect less ionization of atoms and lower electron density in the ionosphere (S. Sharma et al., 2010).…”

“…Just two stations (BRN2 and RMTE) have witnessed eclipse totality, and the remaining three stations have partial solar eclipse (DNGD, NPGJ, and TPLJ). The UNAVCO Data Center handles data management tasks for GPS/GNSS data and products from globally distributed permanent stations [3]. TEQC is the program developed by UNAVCO and supports several GPS tasks that translate to quality control of RINEX and GPS and a calibration method used to obtain TEC.…”

“…It is the longest solar eclipse of the 21st century. There is a decrease in TEC due to the solar eclipse that has been studied by various techniques [2,3], such as measurements derived from the Global Positioning System (GPS). GPS is a tool with the highest accuracy to study the ionosphere dynamics with varying TEC during the eclipse/storm period.…”

“…The ionosphere is a dynamic layer of the upper part of the atmosphere, which generally changes according to radiation emitted by the sun and solar-related ionospheric disturbances. Different natural and artificial phenomena affect the physical and chemical behavior of the ionosphere [1]. Among these, the solar eclipse is a phenomenon that has a direct influence on the Earth's ionosphere.…”
