Altitude profiles of number density and magnetic field within the ionosphere along the subsolar line at 30, 38, 39, 41, 42, and 158 min of simulation. Figures a1, b1, c1, d1, e1, f1 show the altitude profiles of number densities of different ion species and electrons: H⁺ (blue), O⁺ (red), ${\mathrm{O}}_2^{+}$ (black), ${\mathrm{C}\mathrm{O}}_2^{+}$ (pink), and e⁻ (green). Figures a2, b2, c2, d2, e2, f2 are altitude profiles of the induced magnetic field: B_x (blue), B_y (red), B_x (green), and |B| (black). The solid lines depict the profiles of the physical quantities at the times indicated above each panel, while the dashed lines show the corresponding distributions at 30 minutes, serving as a reference of quiet period for comparison.
