NASA satellites have observed the Antarctic ozone hole since the late 1970s—before and after nations agreed to stop producing chemicals that destroy the ozone layer.
Published Sep 18, 2012This series of images shows the Antarctic ozone hole on the day of its maximum depletion in 1979, 1987, 2006, and 2010; that is, the days with the thinnest ozone layer.
Published Feb 1, 2011The smaller ozone hole was strongly influenced by an unstable and warmer-than-usual Antarctic vortex.
Published Nov 3, 2017Ozone depletion was significant in 2013, but less than the long-term average.
Published Oct 26, 2013Does a smaller hole mean that Antarctic ozone is recovering? Not yet, say NASA scientists. A deeper look at the ozone hole shows that for now weather still has a bigger influence on the size of the ozone hole than policies that limited emissions of ozone-destroying chemicals.
Published Dec 19, 2013Blues and purples in this image of Antarctic ozone concentrations reveal the developing ozone hole of 2009.
Published Sep 17, 2009New research from NASA scientists shows that the amount of chlorine in the stratosphere over the South Pole is declining at the same time that ozone holes are becoming less severe.
Published Feb 13, 2018The hole in the ozone layer over Antarctica was slightly above average size in 2018, but smaller than expected for the weather conditions.
Published Nov 14, 2018This image shows the latest data from the Total Ozone Mapping Spectrometer (TOMS) Earth Probe, for the month of October 1999.
Published Nov 15, 1999The Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite acquired data for this map of ozone concentrations over Antarctica on September 12, 2010.
Published Sep 16, 2010The ozone hole over Antarctica grew relatively large and deep in 2015.
Published Oct 27, 2015The annual ozone hole over Antarctica reached its maximum area on September 12, 2011, and its maximum depth on October 9, 2011.
