shibaji7/SolarEclipse: G-Condition Study V2.0

This paper provides the first explanation of the formation mechanism of ionospheric G-condition following a total solar eclipse (TSE) on 21 August 2017, also known as the 2017 Great American Eclipse (GAE). Solar radiation is the primary source of the ionosphere. The eclipse-driven sudden disappearance of solar irradiance of this energy is an opportunity to study how the ionosphere behaves under this controlled environment. Observations showed evidence of the existence of an ionospheric G-condition, where plasma density of ionospheric $F_1$-layer exceeds that of $F_2$-layer, using a radio-sounding instrument following 2017 GAE. Here, we used simulations from a physics-based model to infer the physics behind the formation of ionospheric G-condition. Measurements of overhead ionospheric sounding are compared and analyzed against the simulation results to provide insight into the formation mechanism of the ionospheric G-condition following the 2017 GAE.
