The study investigates the impact of solar storms in April and May 2024 on Earth's upper atmosphere and magnetic field. Data from GPS satellites, ground sensors, and solar wind monitors revealed significant disturbances in the ionosphere. The stronger May storm caused substantial reductions in ionospheric electron content near the equator and a slow recovery, while the April storm increased charged particles at lower latitudes. The study uses a global network of over 80 stations and a novel statistical approach, Z-score normalization with superposed epoch analysis, to detect and interpret disturbances in Earth's magnetic and ionospheric systems.
