Since 1980 the appearance of spring ozone depletion directly caused by chemical removal has significantly changed the pattern of vertical ozone distribution in the antarctic stratosphere, and has become a principal feature of a changing atmosphere. In recent years chemical ozone loss has also been found in the arctic stratosphere. Transient events like the presence of volcanic aerosols can additionally remove ozone in the lower polar stratosphere. Balloon-borne ozone observations and sun photometer measurements performed in the Antarctic and Arctic as well as satellite data are used to review interannual and seasonal changes in the polar stratosphere. For the arctic region tropospheric ozone and aerosol variations are briefly discussed. Some features of polar ozone and the impact of aerosols are discussed by using original results.
