Profile of Ozone Depletion at South Pole Station

Plot of ozone depletion as a function of altitude above South Pole Station.

The greatest depletion of ozone is in the lower stratosphere at altitudes from 10 to 20 km which normally would contain most of the ozone column in polar spring (Jacob, 1999). "Comparison of the South Pole pre­depletion ozone profile in 1993 (average of 4 soundings) with the profile observed when total ozone reached a minimum in 1992 and 1993. (Adapted from (Hofmann et al., 1994).)" (Harris et al., 1995).
