Explore new observations and analyses from inside the Antarctic ozone hole in this 29-minute press conference from the 2013 AGU Fall Meeting. Delve into the internal workings of this annual phenomenon, examining why the holes in 2006 and 2011 were so large and why 2012's was unusually small. Learn about the latest findings on the ozone hole's recovery status and projected trends, more than two decades after the Montreal Protocol limited ozone-depleting substances. Gain insights from NASA scientists Anne Douglass, Natalya Kramarova, and Susan Strahan as they discuss topics including the legacy of space-based metrics, the evolution of the 2012 ozone hole, chlorine and nitrous oxide relationships, and factors influencing hole severity. Understand the current state of stratospheric ozone depletion and when we can expect to see a response in the ozone hole's recovery.
