Short summary
The tropical tropopause is a key region that separates the atmosphere’s two lowermost layers. Ozone concentrations at this level have important implications for atmospheric chemistry and circulation. In this work, we explore how tropical tropopause ozone varies in observations and chemistry-climate models. We show that fluctuations in the elevation of the tropical tropopause play a role in controlling the nearby ozone levels, with implications for future climate and stratospheric ozone.
