Finding the Antarctic Ozone Hole

Keywords: outliers, unusual observations


The story of the how the hole in the Antarctic ozone layer was first discovered, and why it wasn't discovered earlier, is often used as a cautionary tale regarding the treatment of outliers and unusual observations. The cited article below gives some interesting and hard-to-find background to the story.


This example is a story rather than a data set. Read the article by Pukelsheim (1990) below.
