UV Index
The ozone layer shields the Earth from harmful UV radiation. Ozone depletion,
as well as seasonal and weather variations, cause different amounts of
UV radiation to reach the Earth at any given time. Developed by the National
Weather Service (NWS) and EPA, the UV Index
predicts the next day's ultraviolet radiation levels on a 1-11+ scale,
helping people determine appropriate sun-protective behaviors.
