This SOS dataset is a companion to a flat-screen data visualization, Ozone's Slow Recovery, produced by the American Museum of Natural History's Science Bulletins program.
The FTP link will lead you to two movies: One is AMNH's flat-screen visualization. The second-the SOS dataset-adapts this visualization for Science on a Sphere.
Synopsis
Every September and October, a "hole" of varying size emerges in Earth's ozone layer over Antarctica, an effect of a buildup of ozone-depleting human-made chemicals high in the atmosphere. During 2013, the ozone hole reached a maximum size of 20.8 million square kilometers (about 8 million square miles) on September 22. Now that levels of ozone-depleting chemicals are declining as a result of international agreements put in place decades ago, scientists predict that the annual ozone hole is poised to begin a shrinking trend.
