Year-to-Date UV Index Graphs

The plots show the UV index values, measured by Brewer spectrophotometers, as a function of the season and the time of the day over Canadian stations for the current year up to yesterday. The time is shown as a solar time, i.e. the sun is in its highest position over the horizon exactly at noon. The gray areas indicate periods with no observations. The actual spectral UV data are available (with some delay) from the World Ozone and Ultraviolet Radiation Data Center (WOUDC). The UV Index forecast for selected Canadian cities is available from the Canadian Meteorological Centre (CMC).
