Antarctic Ozone Hole in 2009

The stratospheric ozone hole over the South Pole reaches its maximum size each year around mid-September to mid-October. This image, created by combining ultraviolet and infrared data from NOAA's POES satellites, shows the low concentrations of ozone on September 15, 2009. Though some areas of the hole have lower than average concentrations of ozone, for the most part, the hole is close to average for this time of the year. With the exception of 2007 and 2008, the ozone hole appears to be healing overall. More information on ozone monitoring can be found here.
