        Title: Global Ozone during the 2003 Ozone Hole

    Description
      Abstract: This visualization shows the total ozone concentrations for the Earth from August 1, 2003 through September 23, 2003, during the period of the Antarctic ozone hole.  Low ozone (less than 200 Dobson units) is depicted as regions of dark blue, with high ozone (greater that 330 Dobson units) depicted as yellow and red.  The amount of ozone in the stratosphere over Antarctica is reduced during the South Pole winter due to unique atmospheric conditions.  Ozone blocks harmful ultraviolet 'B' rays, and loss of statospheric ozone has been linked to skin cancer in humans and other adverse biological effects in plants and animals.  The size of the 2003 Antarctic ozone hole reached 10.9 million square miles on September 11, 2003, slightly larger than the North American continent.  This data was measured by the TOMS instrument on the Earth Probe satellite.
