World Ozone and Ultraviolet Radiation Data Centre

The World Ozone and Ultraviolet Radiation Data Centre (WOUDC), which began as the World Ozone Data Centre (WODC) in 1961, is one of the World Data Centres associated with the Global Atmosphere Watch (GAW) programme of the World Meteorological Organization (WMO). In June 1992, ultraviolet radiation data was added to the WODC, resulting in the Centre being renamed to the World Ozone and Ultraviolet Radiation Data Centre (WOUDC). The WOUDC is operated by Environment Canada and is located in Toronto.
