The World Ozone and Ultraviolet Radiation Data Centre (WOUDC) is one of the six World Data Centres which are part of the Global Atmosphere Watch (GAW) programme of the World Meteorological Organization (WMO). The WOUDC began as the World Ozone Data Centre (WODC) in 1962 and produced its first data publication of Ozone Data for the World in 1964. In June 1992, Environment Canada agreed to a request from the WMO to add ultraviolet radiation data to the WODC. The Data Centre has since been renamed to the World Ozone and Ultraviolet Radiation Data Centre (WOUDC) with the two component parts: the WODC and the World Ultraviolet Radiation Data Centre (WUDC).
The WOUDC is operated by Environment Canada and is located in Toronto.
