Caption: Arctic ozone hole research. NASA scientist examining "laser ozone mapping experiment" data gathered over the Arctic by a DC-8 flying laboratory in January & February 1989. Initial results from DC-8 and high-altitude ER-2 flights showed a marked increase in concentrations of chemicals known to destroy ozone. Ozone protects us from the Sun's harmful ultraviolet rays. In Antarctica, satellite data has revealed an ozone "hole" that has been growing in size & severity since 1980. Antarctic research in 1987, including ER-2 flights, confirmed that the hole is probably caused by chlorofluorocarbons (CFCs), man-made chemicals used in aerosols & refrigerants.
