Maximum Ozone Hole Extent 1980-2004 (WMS)

The ozone "hole" is not really a hole; it is actually a region with a reduced amount of ozone. The ozone hole is considered to be those areas where the total column ozone is 218 Dobson Units (DU) or lower. This animation shows the maximum extent of the ozone hole in a given year. That is, if on at least one day of the year a measurement pixel had less than 218 DU of ozone, then that pixel is shown as being part of the ozone hole for that year. This animation covers the period 1980-2004, and uses data from the Total Ozone Mapping Spectrometer (TOMS) instruments aboard the Nimbus-7 (1980-1992) and Earth Probe (1996-2004) satellites (data for 1993-1995 are limited and not shown here).

This animation shows the maximum extent of the ozone hole during each year of measurement. Each pixel is 1.25 degrees in longitude by 1.0 degrees in latitude. The white opaque region in the lower part of each image represents the ozone hole extent.
