Stratospheric Ozone and Ultraviolet (UV) Radiation

Stratospheric Ozone and Ultraviolet (UV) Radiation On-going monitoring of the total column ozone and spectral ultraviolet radiation (UV) in Canada is carried out by the Canadian Brewer Spectrophotometer Network (CBSN). The data are used for periodic assessment of the state of the ozone layer, satellite data validation, and in forecasting ECCC’s UV Index. The UV Index values are derived from spectral UV measurements. All locations make total column ozone and spectral UV measurements using Brewer spectrophotometers. Vertical profiles of ozone are ozone mixing ratios as a function of height. They are measured by the Canadian Ozonesonde Network. The data are used for periodic assessments of the ozone layer, various research applications, and satellite validation. All locations measures vertical profiles by launching balloons carrying ozonesondes into the stratosphere, usually once per week. Both total column ozone, UV and ozonesonde data are available from the World Ozone and Ultraviolet Radiation Data Centre (WOUDC) (http://www.woudc.org/), which is hosted by Environment and Climate Change Canada. 2022-02-23 Environment and Climate Change Canada open-ouvert@tbs-sct.gc.ca Nature and EnvironmentAirAir QualityAtmospheric MonitoringNAtChemNetworks and StudiesCanadian Brewer Spectrophotmeter NetworkCSBNCanadain Ozonesonde NetworkAtmospheric Gasesozonestratospheric ozone and ultraviolet radiationUVtotal column ozonevertical profilesBrewer spectrophotometerozonesondeUVUVIUV Index World Ozone and Ultraviolet Radiation Data Centre - Centre mondial de données sur l’ozone et le rayonnement ultravioletHTML https://www.woudc.org/ View EC Data Mart (English)HTML https://data-donnees.ec.gc.ca/data/air/monitor/monitoring-of-atmospheric-gases/stratospheric-ozone-and-ultraviolet-uv-radiation/ View EC Data Mart (French)HTML https://data-donnees.ec.gc.ca/data/air/monitor/monitoring-of-atmospheric-gases/stratospheric-ozone-and-ultraviolet-uv-radiation/?lang=fr
