Peering into the Ozone Hole Peering into the Ozone Hole Concentrations of ozone-destroying gases are down, but the Antarctic ozone hole is bigger than ever. It turns out there's more to ozone destruction than just CFCs.
Scientists have some good news and some bad news for ozone watchers.
That's the good news. Image of the record-size ozone hole taken by NASA satellites on September 9, 2000. Blue denotes low ozone concentrations and yellow and red denote higher levels of ozone. The vertical air currents of tropospheric weather help push CFCs up to the next layer, the stratosphere. Once there, CFCs rise more slowly because stratospheric air has less vertical air movement.
