Short summary

In this study we analysed ozone changes in the tropical mid-stratosphere as observed by the SCIAMACHY instrument during 2004–2012. We used simulations from TOMCAT model with different chemical and dynamical forcings to reveal primary causes of ozone changes. We also considered measured NO₂ and modelled NO_x, NO_x, and N₂O data. With modelled AoA data we identified seasonal changes in the upwelling speed and explained how those changes affect N₂O chemistry which leads to observed ozone changes.
