Peak altitude and amplitude of plasma density and magnetic field magnitude driven by acoustic-gravity waves.

	Electron	O⁺	$O_{2}^{+}$ ${\rm{O}}_2^ +$	${CO}_{2}^{+}$ ${\rm{CO}}_2^ +$	Magnetic field
		Acoustic branch
Peak altitude region (km)	100–170	100–140	95–140	100–140	125–155
Peak amplitude region (%)	1–9	1–5	8.5–10	1–6	0.03–40
		Gravity branch
Peak altitude region (km)	80–130	110–140	80–230	110–230	114–158
Peak amplitude region (%)	5–80	0.25–5	10–80	0.3–7	0.2–17

Notes. To compare with the observational results made by Fowler et al. (2019), the vertical wavenumbers at lower boundary, $k_{z}^{l}$ are fixed at 0.32 km⁻¹ and 0.99 km⁻¹ for acoustic branch and −0.19 km⁻¹ and −0.5 km⁻¹ for gravity branch.
