The Relationship between Polar Vortex and Ozone Depletion in the Antarctic Stratosphere during the Period 1979–2016

<div>Monthly variation of averaged total column ozone (units: DU) within the polar vortex from 1979 to 2016. The contour interval is 20 DU and the values less than 220 DU (Antarctic ozone hole threshold) are shaded with blue color.</div>
