Airglow is a faint emission from the atmosphere. The Andor Airglow Spectrometer measures the spectra of the airglow, whichare used to determine the temperature at ~87km altitude.
We havespectrometer temperature measurements from Rothera Research Station since 2002which enables us to look at long-term changes in the mesosphere temperature and distinguish the contributions from natural and anthropogenic changes. These temperature variations can also be usedto detect gravity waves.
