Caption: Antarctic ozone hole maximum size, 1979-2015. Ozone concentrations are colour-coded, with the purple and dark blue areas representing the lowest levels, constituting the "hole". The hole was first detected in mid 1970s, and was found to be due to chemical reactions between the atmosphere and chlorofluorcarbon gases (CFCs), which were widely used as refrigerants and propellants. CFCs were banned by the Montreal Protocol in 1987. The maximum extent of the hole was recorded in 2006. The measurements were made by NASA’s Total Ozone Mapping Spectrometer (TOMS) instruments, and by the Royal Netherlands Meteorological Institute (KNMI) Ozone Monitoring Instrument (OMI), from 2004-present. Every year from 1979 to 2015 appears in this montage except 1995, for which there is no data.
