Antarctic Ozone Levels 1979 Animation

 

Figure 7e-3: The two spheres above represent the polar view of the South (left) and North Pole (right). In this animation one can see the absence of an area of ozone depletion over Antarctica for the period September 15 to November 15, 1979. The colors in the images represent the quantity of ozone present in Dobson units. See the scale at the bottom of the animation to match the colors displayed with their corresponding Dobson unit value. Shades of medium blue, dark blue, light purple, dark purple and pink represent abnormally low quantities of ozone. Compare this image to the same period in 1992. (Source: NASA).
