Do you know your UV Index?

---

The list of great Canadian inventions is long and varied:

1. Peanut Butter - created in 1884 by Canadian pharmacist Marcellus Gilmore Edson.
2. The Pacemaker – first built in 1949 by Canadian engineer John Hopps, based on observations made by two Toronto-based cardiac surgeons, Wilfred Bigelow and John Callaghan.
3. IMAX - invented by a trio of Canadian filmmakers — Graeme Ferguson, Roman Kroitor and Robert Kerr — in 1967, after being independently asked to produce large-screen films for Expo 67.

But did you know that the UV Index is another great Canadian invention? Developed by three scientists at Environment and Climate Change Canada, Drs. Tom McElroy, Jim Kerr and David Wardle, the UV Index was launched nationally on this day in 1992 in response to concern over the thinning ozone layer. Its success lies in its simplicity as it translates complex scientific information on the ozone layer and the strength of the sun’s rays into a simple numeric scale.
