\textbf{SA comments: I think the structure of the results should be thus. (a) One or two case studies, for example the Melbourne cut-off low, see Fig 3 in your summer report, and a second case study showing STT / O3 intrusion related to a cold front (Melbourne, or if possible, Macquarie or Davis...). For each case study, show vertical ppbv profile of O3 (and T if you want, like Fig 2 in your summer report), and a mid-tropospheric weather map (like FIg 3 in your report) to show the synoptic meteorology. I'll help with the text talking about these plots.}  \textbf{The next 3 plots will be your event summaries, as you have presented below. Some minor points: label in the titles the sub-=panels as (a), (b) etc. for easy reference in the text. Also x-axis of lower right sub-panel (the tropopause to event peak), change to 'km below the tropopause' and change y-axis to 'frequency of occurrence' (also make this cahnge to the 'event altitudes' y-axis). I will add some initial commentary on these plots below shortly}  \textbf{Then perhaps the next plot will be your Fig 5 from your summer report, i.e. the frequency of occurrence of shallow, medium and deep intrusions. I think this worth showing. What do you think?}  \textbf{Last plot will be your nice summary plot of tropospheric ozone from STTs, as in Fig 5 below.}  The event summaries for each of the three locations are presented in Figure~\ref{fig:SummaryMelbourne} to Figure~\ref{}. There is an annual cycle in the occurrence frequency of STT events with a summertime peak above Melbourne and Macquarie Island. However, the occurrence frequency of STT events above Davis is relatively constant throughout the year.  The majority of events are shallow, occurring within XX~km of the tropopause.  Melbourne events coincide with low pressure fronts and cut-off lows.  Using our filter on 458 profiles between 2004 and 2014 found 73 events contributing at least an average of 2.7\% of the tropospheric ozone. The seasonal distribution can be seen in panel two(clockwise) of figure \ref{fig:SummaryMelbourne} and shows January February and March exhibit the most ozone intrusions. 

Davis events are more evenly distributed.
