The atmospheric ozone band shields all forms of life on earth from harmful ultraviolet radiation.

In 1946 Normand moved to Oxford, where he studied atmospheric ozone.

ERS-2, launched in 1995, provides data related to ocean surface temperature, winds at sea and atmospheric ozone.

Correspondingly, a significant decrease in atmospheric ozone could be expected to give rise to significantly increased levels of UV near the surface.

Federal scientists reported today that atmospheric ozone over the Northern Hemisphere had declined significantly over the last two decades.

Scientists estimate that for every 1 percent decline in atmospheric ozone, 2 percent more ultraviolet radiation reaches the earth's surface.

The concern then was the depletion of atmospheric ozone; the issue now is ground-level smog.

The instrument also gives scientists their best view of atmospheric ozone in the Antarctic region during the polar winter.

Why do we care about atmospheric ozone?

An example is the Dobson unit for atmospheric ozone.
