30 years already for our UV Index!
On May 27, 30 years ago, Canada became the first country in the world to add the UV Index to its weather forecast as a tool to help Canadians understand the dangers from sun’s overexposure. It was invented by three of our scientists, Drs. Tom McElroy, Jim Kerr and David Wardle, in response to concerns over the thinning ozone layer. The great success of the UV Index over the years lies in its simplicity: it translates complex scientific information on the ozone layer and the strength of the sun’s rays into a simple numeric scale.
