Orbital variability of the mass fluxes, in kilograms per Earth-day. Panel (a): mass fluxes of meteoroids before atmospheric entry for the JFCs (blue line), ASTs (green line), HTCs (dark red line), OCCs (orange line), and total mass input (black line). Panel (b): mass fluxes of total MMs (gray line), total ablated (solid red line), neutral atoms (dashed light-blue line), and ionized atoms (dashed light-green line).
