This animation shows total ozone in the Antarctic region along with the maximum ozone depth and size since the earliest measurements of the TOMS instrument on the Earth Probe satellite. This animation was created for an exhibit at the Smithsonium Museum.

The TOMS instrument on the Earth Probe spacecraft has recorded daily ozone values from July 25, 1996. Areas of red show the highest concentration of ozone measured in dobson units, DU. Areas of purple indicate the lowest concentration, commonly known as the ozone hole. The top plot shows the amount of ozone concentration measured in DU. The bottom plot shows the spatial area in Millions of Kilometers, MKm, of the ozone hole.

Legend for Ozone animation. 'DU' stands for Dobson Units, a standard unit for measuring ozone concentrations.
