Earth Exploration Toolbook Chapter: Analyzing the Antarctic Ozone Hole DLESE Reviewed Collection
In this activity, users examine satellite images from NASA's Total Ozone Mapping Spectrometer (TOMS) that show how much ozone is in the atmosphere over the Southern Hemisphere. They interpret the images to identify ozone thinning that develops over this region 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 into a spreadsheet program and create a graph to document changes in the size of the ozone hole.
