The animation on the right had all the data 'imperfections' removed by interpolation, under the assumption that the viewer would only have 20 or 30 seconds to look at it (on the evening news, for example) with only the briefest of explanations. The problem was that, without explanation, a layman might interpret the region of missing data in the movie on the left to be the ozone hole, instead of the central blue region.

is the largest ever observed. Scientists continue to investigate the phenomenon, and are somewhat surprised by its scale. Using data from NASA's Total Ozone Mapping Spectrometer (TOMS) instrument onboard the Earth Probe satellite, researchers can evaluate and compare current conditions over the south pole to readings taken by other instruments in years past. Continued monitoring of polar ozone levels helps researchers gain a better understanding of how the planet's climate may be changing. The following animation shows how ozone loss at the south pole has grown since the mid-80s. Early readings over Antarctica indicate little or no ozone depletion beyond naturally predicted levels. But as the 80s and 90s progress, a clear change in atmospheric chemistry takes place at the bottom of the world. The hole starts small in the late 80s and spreads as subsequent winter cycles break apart ozone molecules. || ", "release_date": "2002-10-09T12:00:00-04:00", "update_date":
