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

EDITORS COMMENTS
This print showcases a series of satellite maps comparing the Antarctic ozone hole from 1987 to 1990. The severe depletion or "hole" in the ozone layer over Antarctica is clearly visible on each 3rd October during this period. Initially observed in 1980, scientists believe that this alarming phenomenon is primarily caused by pollution of the atmosphere due to chlorofluorocarbons (CFCs) used in aerosols and refrigerants. The image depicts the ozone hole appearing in striking shades of pink, with the outline of Antarctica boldly outlined in black. Interestingly, the size of the hole remained relatively consistent between 1987,1989, and 1990. However, there was a noticeable reduction in its size during 1988. These thought-provoking maps were created using data collected by the Total Ozone Mapping Spectrometer (TOMS) aboard the American Nimbus-7 weather satellite. TOMS plays a crucial role in monitoring and studying Earth's atmosphere for signs of pollution and environmental changes. As we delve into this visual representation captured by Science Photo Library, it serves as a stark reminder of how human activities can have far-reaching consequences on our planet's delicate ecosystems. It underscores the urgent need for global cooperation to combat pollution and protect our invaluable ozone layer – an essential shield safeguarding life on Earth from harmful ultraviolet radiation.
