Thirty years ago, the nations of the world agreed to the landmark ‘Montreal Protocol on Substances that Deplete the Ozone Layer.’ The Protocol limited the release of ozone-depleting chlorofluorocarbons (CFCs) into the atmosphere. Since the 1960s, NASA scientists have worked with NOAA researchers to study the ozone layer, using a combination of satellite, aircraft and balloon measurements of the atmosphere. Things have been improving in the 30 years since the Montreal Protocol. Thanks to the agreement, the concentration of CFCs in the atmosphere has been decreasing, and the ozone hole maximum has been smaller since a record in 2006. From the ground and space, NASA science offers a unique perspective of Earth, helping to identify challenges and find solutions to benefit the planet.
