Ozone hole over Antarctica
Satellite map showing a severe depletion or " hole" in the ozone layer over Antarctica on October 3rd, 1990. The hole is believed to be due to pollution of the atmosphere by chlorofluorocarbons used in aerosols & refrigerants. First observed in 1980, the most severe depletion was recorded in October 1987. This image represents the maximum depletion during the Antarctic spring of 1990. It appears here as the violet & pink areas covering Antarctica (outlined in white) & beyond. The scale of colours represents Dobson units, a measure of atmospheric ozone. The map was made by the Total Ozone Mapping Spectrometer (TOMS) on the American Nimbus-7 weather satellite

EDITORS COMMENTS
This print showcases the alarming state of the ozone layer over Antarctica on October 3rd, 1990. The image reveals a severe depletion or "hole" in the ozone layer, which is believed to be a direct consequence of atmospheric pollution caused by chlorofluorocarbons (CFCs) used in aerosols and refrigerants. This phenomenon was first observed in 1980, with the most extreme depletion recorded in October 1987. However, this particular snapshot represents the maximum level of depletion during the Antarctic spring of 1990. The violet and pink areas covering Antarctica (outlined in white) depict the extent of this concerning hole, extending beyond its borders as well. The color scale utilized here represents Dobson units - a measurement unit for atmospheric ozone concentration. Captured by the Total Ozone Mapping Spectrometer (TOMS) aboard the American Nimbus-7 weather satellite, this satellite map offers invaluable insights into our planet's delicate ecosystem. It serves as a stark reminder of how human activities can significantly impact Earth's climate and environment. This thought-provoking photograph from Science Photo Library highlights not only scientific data but also raises awareness about pressing issues such as pollution and climate change that demand immediate attention from individuals and governments alike.
