Low ozone measured over north pole
News story originally written on April 8, 1997

Very low levels of ozone were measured over the Arctic during March by several satellites. Ozone is a chemical that is in the Earth's stratosphere. It protects us from harmful solar radiation.

Though the levels of ozone at the northern ice cap are much higher than those in the Antarctic, they are very unusual. The levels of ozone are 40% lower than those measured between 1979-1982.
