Short summary

The mechanisms that produce, destroy and transport nitric oxide (NO) in the Antarctic mesosphere and lower thermosphere are investigated in AIM-SOFIE satellite observations and compared to SD-WACCM simulations. During winter, NO concentrations are most similar while the altitude of maximum NO number densities is most separated. Even though the rate of descent is similar in both datasets, the simulated descending NO flux is too low in concentration, which reflects a missing source of NO.
