Accurate models of atmospheric transport are crucial to our current understanding of ozone production/loss and its coupling
with climate change. Over the last ``20 years'', improvements in the ability to predict ``The Antarctic Ozone Hole and Polar
Ozone Loss'' have tracked improvements in transport models. Data taken from the NOAA/CMDL airborne in-situ GC's (ACATS,
LACE, PANTHER, and UCATS) have and will continue to play key roles in quantifying many aspects of stratospheric transport.
Our data have been used in many of the model assessments to date. We will display an overview of the transport issues
studied over the years using our data. They include descent with mixing within and into the polar vortex, entrainment of
mid-latitude air across the vortex edge, upwelling and entrainment in the tropical pipe, isentropic transport across the
tropopause into the lowermost stratosphere, mean ages of air parcels in the stratosphere, and stratospheric path
distributions.
