Users download and analyze satellite images showing the amount of ozone in the stratosphere. They interpret the images to identify the ozone "hole" that develops over Antarctica each summer, and compare its size from year to year. Using freely available image analysis software, ImageJ, users quantify the area of the Antarctic ozone hole each October from 1996 to 2004. Finally, they bring their measurements ...
