Short summary

Ozone (O₃) is an important trace gas in the mesosphere and lower thermosphere (MLT), affecting heating rates and chemistry. O₃ profiles measured by the Ny-Ålesund Ozone in the Mesosphere Instrument agree with Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) for winter night-time, but autumn twilight SABER abundances are up to 50 % higher. O₃ abundances in the MLT from two different SABER channels also show significant differences for both autumn twilight and summer daytime.
