Solar events such as solar flares and coronal mass ejections (CMEs) introduce dynamic changes in the thermosphere’s composition through enhanced particle precipitation, X-ray, and extreme ultraviolet radiation. This paper explores the variations in thermospheric constituents—particularly atomic oxygen (O), nitrogen (N2), and helium (He)—during geomagnetic storms using remote sensing techniques. Ground-based Fabry-Perot interferometry, satellite-based EUV sensors, and GNSS TEC analysis were utilized to detect and quantify compositional changes over South Asia, especially Pakistan. Results reveal a substantial decrease in atomic oxygen density and corresponding thermospheric cooling during high-intensity events. The study underscores the need for continuous monitoring using integrated satellite-ground observational systems.
