Abstract

One of the objectives of the Airborne Southern Hemisphere Ozone Experiment (ASHOE) was to examine the causes of ozone loss in the Southern Hemisphere lower stratosphere, and to investigate how the loss is related to polar, mid-latitude, and tropical processes, including radiative transfer. Cooling rates were calculated for ASHOE in order to: (1) understand how the ozone depleted air is transported to populated regions outside the polar vortex, (2) relate vertical motions and transport of air around the South Pole to atmospheric cooling rates, and (3) validate cooling rates in dynamical models for the polar vortex using observed data and more accurate radiative transfer models.
