Short summary
In 1926, total ozone series started in Arosa (Switzerland). Since the mid-1970s ozone is measured to document the effects of anthropogenic ozone-depleting substances (ODSs). ODSs peaked around the mid-1990s, resulting from the Montreal Protocol (1987) and its enforcement. Chemical ozone depletion stopped worsening around the mid-1990s but the large variability complicates demonstrations of the success of the protocol and the effect of ongoing climate change still requires continuous measurement.
