World Ozone and Ultraviolet Radiation Data Centre (WOUDC)

Home

The World Ozone and Ultraviolet Radiation Data Centre (WOUDC) is one of five World Data Centres which are part of the Global Atmosphere Watch (GAW) programme of the World Meteorological Organization (WMO). The WOUDC is operated by the Experimental Studies Division of the Meteorological Service of Canada (MSC) — formerly Atmospheric Environment Service (AES), Environment Canada and is located in Toronto.

The WOUDC began as the World Ozone Data Centre (WODC) in 1960 and produced its first data publication of Ozone Data for the World in 1964. In June 1992, the AES 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).

There are presently six ozone data categories (types) and three UV data types registered at the WOUDC. The ozone data archive contains the following data categories: Lidar vertical profiles, Ozonesonde vertical profiles, Total column ozone (Daily and Monthly values), Surface ozone (Daily summaries), and Umkehr N-value and C-Umkehr vertical profiles. The UV data archive contains the following data categories: Broad-band, Multi-band and Spectral.
