Snapshot of the Antarctic Ozone Hole 2010 [HD Video]
Today, September 16, is the International Day for the Preservation of the Ozone Layer, a commemoration of the day in 1987 when nations commenced the signing of the Montreal Protocol to limit and eventually ban ozone-depleting substances such as chlorofluorocarbons (CFCs) and other chlorine and bromine-containing compounds. The Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite acquired data for this map of ozone concentrations over Antarctica July 1, 2010 thru September 13, 2010.
The yearly depletion of stratospheric ozone over Antarctica – more commonly referred to as the “ozone hole” – started in early August 2010 and is now expanding toward its annual maximum. The hole in the ozone layer typically reaches its maximum area in late September or early October.

NASA Goddard atmospheric scientists are active members of the International Ozone Commission and the ozone scientific assessment panel for the United Nations Environment Program, which monitors the effectiveness of the Montreal Protocol.
