The World Ozone and Ultraviolet Radiation Data Centre (WOUDC) is one of six World Data Centres which are part of the Global Atmosphere Watch programme of the World Meteorological Organization. The WOUDC data centre is operated by the Meteorological Service of Canada, a branch of Environment and Climate Change Canada.
Ozone data set categories include total column ozone and vertical profile data from lidar measurements, ozonesonde flights, and the Umkehr technique. Ultraviolet (UV) radiation data set categories include broadband, multiband, and high resolution spectral data types.
Value added data products include total ozone time series graphs and near real-time ozone maps.
All WOUDC data are made available by using the data search / download, or web accessible folder (WAF) access. In addition, the Open Geospatial Consortium web services provide enhanced access to the archive, which provides standards-based-on-demand access to the archive.
