160658main2 OZONE large 350.png
English: From September 21-30, 2006 the average area of the ozone hole was the largest ever observed, at 10.6 million square miles (27.5 million square kilometres). This image, from September 24, the Antarctic ozone hole was equal to the record single-day largest area of 11.4 million square miles (29.5 million square kilometres), reached on Sept. 9, 2000. Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone. The blue and purple colors are where there is the least ozone, and the greens, yellows, and reds are where there is more ozone.
