![]() The World Ozone and Ultraviolet Radiation Data Centre (WOUDC) is an official WMO (World Meteorological Organization) repository for measurements of stratospheric ozone.Variations in weather conditions play an important role in determining ozone concentrations. average) thickness of the ozone layer for each month of the year. Maps of the Northern Hemisphere, Southern Hemisphere and the Earth, showing the normal (i.e. Shown as absolute amounts, or deviation from normal for the day of the year. Maps of yesterday and the day before of the thickness of the ozone layer over the Northern Hemisphere, or Southern Hemisphere, or the Earth. Similar to the Ozone Map Archive, but maps are prepared from individual measurement sources. These maps are a blend of observations from several sources. ![]() The archive of ozone-layer maps of the Northern Hemisphere, Southern Hemisphere or the Earth, either as an absolute thickness, or compared to the normal for that day of the year, for every day since 1970. The World Meteorological Organization has assigned them to manage the World Ozone and Ultraviolet Radiation Data Centre, and through it a World Ozone Mapping Centre. It is managed by Environment Canada personnel.Įnvironment Canada scientists work with scientists in many other countries and organizations. The World Ozone and Ultraviolet Radiation Data Centre (WOUDC) is an official WMO (World Meteorological Organization) repository for measurements of UV radiation. WOUDC - The World Ozone and Ultraviolet Radiation Data Centre.There is a form where you can vary such things as the altitude and the thickness of the ozone layer, which change the UV index. ![]() Then you can click on a date on the graph and it gives you another graph showing how the UV index varies during the day. It shows you a time-series graph of the maximum (noon) UV index for each day of the year at that location. You are presented with a map of the world, from which you click on a location. Presented as three-dimensional graphs, with the x-axis being day of the year, the y-axis being time of the day, and the UV index for each day and time being shown as a colour. The UV index measured by Brewer Spectrophotometers in the Canadian network for the year to date. Presented as time series graphs showing three types of information. The maximum daily UV index measured by Brewer Spectrophotometers in the Canadian network for the year to date.
