Lead
Since Wikipedia is more of an encyclopedia, it might be better to start off by summarizing/defining Tropospheric ozone depletion events rather than ozone itself.

Content
The content seems up to date and is relevant

Tone and Balance
The tone is neutral and balanced. In the second paragraph you mention that the mechanisms are "debatable." I suggest either changing it to say debated and then explaining what different viewpoints are, or change to wording to say that the mechanisms aren't fully understood yet.

Sources and References
There is a good range of sources that include current and more historical sources. Paragraph 3 has a stretch of sentences with no citations, I would add sources there.

Organization
I think that adding headings would help the organization of the article. A "Lead" section where you summarize what tropospheric ozone depletion events are and then maybe a "chemistry" heading and a "causes" heading? You probably know better than I do on what headings make sense.

Images/Media
Good figure! I think this complements the chemistry explanation well :)

Overall Impressions
You've done a great job taking a really underdeveloped article and expanding it! My main suggestions are to add headings and a few more citations. Other than that, I think its great! Good work :)
