This computer image shows the total quantity of ozone over the region near the South Pole, with various colors corresponding to Dobson units (equivalent to the thickness, in units of 10 mm, of total ozone in the atmosphere,assuming it to be compressed to 1 atm at 0°Q.The ozone hole is shown in dark blue,equal to 200 to 225 Dobson units. In September 2002,the ozone hole split into two parts. Data were obtained by theTotal Ozone Mapping Spectrometer (TOMS) aboard the Earth Probe satellite.
