A large thin spot in the ozone layer above Antarctica is highlighted in blue in this 2010 picture created from measurements by NASA's orbiting Total Ozone Mapping Spectrometer (TOMS) instrument.
For revealing the chemical reactions behind ozone-layer damage, researchers Paul Crutzen, Mario Molina, and Sherwood Rowland were awarded the 1995 Nobel Prize in Chemistry. The trio's work showed, among other things, how sensitive the ozone layer is to man-made aerosols.
"Their work established the chemistry of the atmosphere that ... led to sensible policies to control ozone-layer damage," such as bans on certain aerosol products, Tritton said...
