Short summary
This research explores how hydrogen ions and oxygen ions move and gain energy in Earth’s magnetosphere at high altitudes and latitudes. Using Monte Carlo simulations, predictions of mean particle theory, and corresponding observations, we compared different energy profiles of hydrogen and oxygen ions across polar-wind, aurora, cusp, and central-polar-cap regions. Our findings reveal that unique interactions in each area affect energy gain differently, with implications for future space weather models.
