September 16th is the International Day for the Preservation of the Ozone Layer, celebrating the 35th signing anniversary of the 1987 Montreal Protocol treaty on Substances that Deplete the Ozone Layer. We would like to report success in the reduction of the ozone-depleting substances (ODSs) in the stratosphere by about 25 % since their peak in the late 1990s, which sets the ozone layer on the path of recovery by 2060.
The International Ozone Commission was established in 1948 as one of the special commissions of the International Union of Geodesy and Geophysics, who represent the entire community of geophysical scientists around the world. The purpose of the IO3C is to help organize the study of ozone around the world, including ground-based and satellite measurement programs and analyses of the atmospheric chemistry and dynamical processes affecting ozone.
