Daily Erythemal Index (UV exposure) Measurements for 2000-2001 (WMS)

Abstract:: The Erythemal Index is a measure of ultraviolet (UV) radiation at ground level on the Earth. (The word erythema means an abnormal redness of the skin, such as is caused by spending too much time in the sun--a sunburn is damage to your skin cells caused by UV radiation.) Atmospheric ozone shields life at the surface from most of the harmful components of solar radiation. Chemical processes in the atmosphere can affect the level of protection provided by the ozone in the upper atmosphere. This thinning of the atmospheric ozone in the stratosphere leads to elevated levels of UV at ground level and increases the risks of DNA damage in living organisms.

Abstract:: Students explore the causes and effects of the Earth's ozone holes through discussion and an interactive simulation. In an associated literacy activity, students learn how to tell a story in order to make a complex topic (such as global warming or ozone holes) easier for a reader to grasp.

Abstract:: Discussion of holes in the stratospheric ozone layer usually revolves around investigations of the thickness of the layer near the South Pole. This online activity allows users to study the thickness of the ozone layer over any location on Earth.
