Temporal variations in (a) the escape rates in heavy ions and (b, c) the corresponding upstream solar wind plasma and IMF conditions. Panel (a) shows the escape rates of O⁺ (black), ${\mathrm{O}}_2^{+}$ (red), and ${\mathrm{C}\mathrm{O}}_2^{+}$ (green). The dashed lines represent the escape rates of O⁺, ${\mathrm{O}}_2^{+}$, and ${\mathrm{C}\mathrm{O}}_2^{+}$ under typical quiet solar wind conditions for reference. Panel (b) shows IMF By and Bz components, and Panel (c) displays solar wind plasma density and velocity.
