Abstract
Abstract 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.
期刊介绍：
Atmosphere-Ocean is the principal scientific journal of the Canadian Meteorological and Oceanographic Society (CMOS). It contains results of original research, survey articles, notes and comments on published papers in all fields of the atmospheric, oceanographic and hydrological sciences. Arctic, coastal and mid- to high-latitude regions are areas of particular interest. Applied or fundamental research contributions in English or French on the following topics are welcomed:
climate and climatology;
observation technology, remote sensing;
forecasting, modelling, numerical methods;
physics, dynamics, chemistry, biogeochemistry;
boundary layers, pollution, aerosols;
circulation, cloud physics, hydrology, air-sea interactions;
waves, ice, energy exchange and related environmental topics.
