World Ozone and Ultraviolet Radiation Data Centre

The World Ozone and Ultraviolet Radiation Data Centre (WOUDC) is operated by the Experimental Studies Division of the Meteorological Service of Canada (MSC), until recently known as the Atmospheric Environment Service, Environment Canada. The Data Centre began as the World Ozone Data Centre (WODC) in 1960 and in June 1992, the MSC agreed to a request from the WMO to add ultraviolet radiation data to the WODC. The Data Centre has since been renamed 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 WODC operates a scientific archive and database providing a variety of ozone data sets to the international scientific community. Some data records date back more than 40 years. Data sets include total column ozone and vertical profile data from ozonesonde flights, lidar measurements and the Umkehr technique. Archived data are available by conventional FTP access or by a direct link from the WOUDC Data Web page. At present, access to the archive by conventional FTP requires a username and password, which is available upon request. Value added data products include total ozone time series graphs and near real-time ozone maps.

The WUDC like its ozone counterpart, is a scientific archive and database of high resolution spectral, multi-band and broad-band UV data. The database started receiving data in early 1993.

At present, there are over 400 registered stations represented in the WOUDC archive. Metadata information such as station lists with locations, are available from the WOUDC Web site.
