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.
