Title
Hole in the Ozone Layer Over Antarctica
Full Description
In 1985, a British scientist working in Antarctica discovered a
40 percent loss in the ozone layer over the continent. When
Goddard Space Flight Center researchers reviewed their data,
they confirmed the ozone loss. Since then, scientists have
relied on instrumentation developed by Goddard to keep track of
the environmental phenomenon, which in the 1990s prompted a
worldwide ban on chlorofluorocarbons (CFCs), a chemical used for
refrigeration and other industrial uses. In this image, the
blue/purple areas show low ozone, while the red areas indicate
higher ozone levels. Although ozone is considered a pollutant in
the troposphere?the atmospheric layer that contains the air we
breathe?in higher altitudes, notably in the stratosphere, ozone
is considered vital. Stratospheric ozone blocks harmful
ultraviolet radiation produced by the Sun. Scientists worry that
the large ozone opening over the poles generally deplete ozone
levels around the globe, which could cause a health risk to
animals and plants.
