• Ozone decline observed in the stratosphere over the past three decades has resulted from the accumulation of chlorine- and bromine-containing ozone-depleting substances (ODSs) in the atmosphere. Production of most of these gases is regulated by the Montreal Protocol and its Amendments and Adjustments. The latest observations show a decline in major ODSs in the troposphere as a result of these regulations. Observed changes in global ozone are in line with those expected based on changes in stratospheric levels of chlorine and bromine. A change in the rate of ozone decline was observed in the mid-1990s. This paper gives a brief overview of the present knowledge of distribution, variability, and long-term trends in column ozone and ozone profiles, with a focus on observational results and particularly on Canadian data analysis.
