Interesting so I looked it up.

The Ultraviolet (UV) Index, developed in 1994
by the National Weather Service (NWS) and the
U.S. Environmental Protection Agency (EPA),
helps Americans plan outdoor activities to avoid
overexposure to UV radiation and thereby lower
their risk of adverse
health effects. UV radiation
exposure is a risk
factor for skin cancer,
cataracts, and other illnesses.
The incidence of
skin cancer, including
melanoma, has increased
significantly in the United
States since the early
1970s.

Graphs of the UV Index forecast and "clear sky" UV Index forecast over the course of a year are available. Use the table of cities below to view a city's UV Index time series for a particular year. Each time series runs from January 1 through December 31. Within the graph, the ranges of exposure (minimal, low, moderate, high and very high) are colored. At the bottom of each graph is an accounting of the number of days the UV Index was in a certain exposure range.
