Short summary

The composition of the upper atmosphere has been difficult to measure with localised observations relying on spacecraft, suborbital rockets or measurements of airglow from ground-based observatories. The height profile of ionisation within the neutral upper atmosphere is influenced by the composition of the neutral gas. We present a method for determining the neutral upper-atmosphere composition from measurements of the ionisation profile and compare these with spacecraft measurements.
