Short summary

We quantify the relative contribution of processes controlling the interannual variability (IAV) of tropospheric ozone over the southern hemispheric tropospheric ozone maximum (SHTOM) with GMI chemistry transport model. We use various GMI tracer diagnostics, including a StratO₃ tracer to quantify the stratospheric impact, and tagged CO tracers to track the emission sources. Our result shows that the stratospheric contribution is the most important factor driving the IAV of upper tropospheric O₃.
