This image is part of the feature Ozone Hole 1994


Caption: The Ozone hole over Antarctica (grey, pink and purple area at centre) as recorded on October 2nd 1994. The colours represent total ozone concentra- tion measured in Dobson Units (DU) running from grey for the lowest concentration through pink, yellow, green and brown for the highest. Land boundaries are shown as solid white lines. The ozone hole covers about 24 million square kilometres, similar in extent to the record sizes seen in 1992 and 1993, and almost fills the maximum possible extent of the hole (governed by the position of the circumpolar vortex winds). The data were taken by NASA's Total Ozone Mapping Spectrometer on the Russian Meteor-03 satellite.
