Antarctic ozone hole: TOMS comparison 1987-1990

Series of satellite maps comparing the severe depletion or "hole" in the ozone layer over Antarctica on each 3rd October in the period 1987- 90. First observed in 1980, the hole is believed to be due to pollution of the atmosphere by chlorofluorocarbons (CFCs) used in aerosols & refrigerants. The hole appears in shades of pink, with Antarctica outlined in black. The size of the hole was similar in 1987, 1989 & 1990, whilst in 1988 it was reduced. The map was made by the Total Ozone Mapping Spectrometer (TOMS) on the American Nimbus-7 weather satellite
