2013-11-04: OMI - News: Antarctic Ozone Hole in 2013

According NASA's Ozone Hole Watch team and based upon a combination of ozone column data from OMI and from the Ozone Monitoring and Profiler Suite (OMPS) on the NASA-NOAA Suomi NPP satellite, the ozone hole over Antarctica was slightly smaller in 2013 than the average for recent decades. The combined set of satellite data showed an the average size of the hole in September-October 2013 of 21.0 million square kilometers. The average size since the mid 1990s is 22.5 million square kilometers.

The single-day maximum area reached 24.0 million square kilometers on September 16, an area about the size of North America. The largest single-day ozone hole ever recorded by satellite was 29.9 million square kilometers (11.5 million square miles) on September 9, 2000.

According to these data, the ozone hole covered 19.2 million square kilometers on this date. The minimum ozone column of 145 Dobson Units was found at 19.5 degrees East, -79.0 degrees South. At the South Pole the ozone column was 190 Dobson Units.
