Arctic ozone loss visualized

This new video from NASA Goddard contrasts the dynamics of the Arctic ozone layer in 2010 to 2011. Running from January 1 to March 23 the two maps are based on observations from the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite

According to NASA Goddard, this information, along with measurements from other satellites and ground stations, suggests ozone levels above the Arctic are approaching a record low. The possibility of an ozone hole developing can’t be ruled out. However…

On a global scale, the ozone layer is still on a long-term course for recovery. But for decades to come, there remains a risk of major ozone losses on yearly or regional scales.

As Goddard atmospheric scientist Paul Newman explains:

The ozone layer remains vulnerable to large depletions because total stratospheric chlorine levels are still high, in spite of the regulation of ozone-depleting substances by the Montreal Protocol. Chlorine levels are declining slowly because ozone-depleting substances have extremely long lifetimes.
