Ozone Hole: NOAA, NSF OBSERVE 20TH ANNIVERSARY OF OZONE HOLE 'SUCCESS STORY': "Twenty years ago this month, four teams of scientists from NOAA, NASA and two universities arrived in Antarctica seeking to determine the cause of a 'hole' in the Antarctic ozone layer. Their efforts helped determine the chemical basis for the ozone loss and formed the scientific basis for the resulting international treaty phasing out the production of chlorofluorocarbons, or CFCs, which has led to a decline in ozone-depleting gases."
