The chemistry of the middle atmosphere is very complex, involving many gases. Accurate measurements of a large number of trace molecules are needed to verify computer models of how that chemistry works, so atmospheric changes which occur naturally can be distinguished from those that are induced by human activity. Already, the device has provided additional data on atmospheric trace gases in near real-time. This information should help the scientists to distinguish those processes induced by solar activity from those caused by human activities. The device has completed over 6000 measurements of variations in the distribution of trace gases at heights between 30 and 150 km with a resolution of 1.5 km.
Hydroxyl plays a key role in the natural destruction of ozone.
Then, the mission's second solar pointing period will begin.
