Ground level ozone and meteorological parameters were measured at the Mount Sutton research site from October 1986-June 2008. The main objectives of these measurements were:

  1. to characterize high elevation (845 m.a.s.l.) ozone levels in this rural region; and 2. to determine long term ozone trends, particularly background levels. Ozone was measured with a commercial Thermo Environmental Instruments Model 49 instrument based on the principle of ultraviolet absorption by Ozone.

The Canadian Brewer Spectrophotometer Network (CBSN) monitors the total thickness of the ozone layer (known as total column ozone) and ultraviolet (UV) radiation at selected monitoring locations across Canada. The objectives of the network are to provide long-term stratospheric ozone data for periodic assessment of the state of ozone layer; use the data for validating satellite ozone data (total ozone and UV); and provide long-term data of spectral UV for biological effect studies (e.g., vitamin D production), ozone data for Environment Canada UV index forecasts, and data for studying current and emerging issues such as climate change (stratosphere).

Ground level ozone (GLO3) was measured at the Alert, Nunavut research station (82º28’N, 62º30’W) from 31 December 1991 to 31 December 2003. These measurements were conducted to: 1. determine a long term trend in background ozone, and 2. to understand the annual appearance of surface level ozone depletions that start in mid-March ( just after the time of polar sunrise) and extend into June. Ozone depletion events have also been correlated with atmospheric mercury depletion events. Many field studies have been carried out at Alert to unravel the reason for this phenomenon.

The Canadian Ozonesonde Network measures vertical profiles of ozone from ground level up to 36 km altitude across Canada. The objectives of the network are to provide long-term stratospheric and tropospheric ozone data for periodic assessment of the state of the ozone layer, to validate satellite ozone data and air-quality model output, and to provide data for chemical data assimilation and for studying current and emerging issues such as climate change.

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.

Trace gas data sets measured by Canadian and U.S. ground-based monitoring networks from 1982 to the present including non-methane hydrocarbons (NMHC), ozone (O3) and total gaseous mercury (TGM). Included are Canadian federal and provincial networks (past and present) and U.S. historical networks (for data not available elsewhere). These data sets are associated with various networks that monitor a variety of trace and reactive gases. Non-Methane Hydrocarbons were measured and monitored in a study at Egbert, Ontario at the Centre for Atmospheric Research and Experiments, CARE.
