In the oil sands air monitoring component, nitrogen dioxide (NO2) and sulphur dioxide (SO2) levels are monitored by ground-based instruments, satellites and other measurements. Monitoring of air pollutants from satellites is becoming an alternative to surface and aircraft measurements, and allows...

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...

Black carbon is a short-lived, small aerosol (or airborne) particle linked to both climate warming and adverse health effects. It is emitted from incomplete combustion of carbon-based fuels (i.e., fossil fuels, biofuels, wood) in the form of very fine particulate matter. Black carbon is not...

Ambient concentrations of speciated mercury (Hg) have been measured at many locations across Canada. Mercury in the atmosphere is measured in three operationally-defined forms - gaseous elemental mercury (GEM), reactive gaseous mercury (RGM), and particulate-bound mercury (PBM). Under most...

Environment and Climate Change Canada (ECCC) began ambient air monitoring of several nitrogen and sulphur species southeast of the Athabasca oil sands region in February 2015. Continuous measurements of NO, NO2, NOy, NH3, and SO2 are currently being conducted at two sites in Saskatchewan....

The Air Quality Health Index (AQHI) is a scale designed to help quantify the quality of the air in a certain region on a scale from 1 to 10. When the amount of air pollution is very high, the number is reported as 10+. It also includes a category that describes the health risk associated with the...

The Air Pollutant Emission Inventory (APEI) is an annual report of air pollutant emissions across Canada published by Environment and Climate Change Canada. The report details the release of air pollutants from all known of sources since 1990. The APEI serves many purposes, including:...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Air health trends indicators were developed as a tool to monitor trends in public health impacts in Canada attributable...

During August 2013, September 2013, April 2018, May 2018, and June 2018, a research aircraft was deployed in the oil sands region. The flight paths of the aircraft were designed to measure air pollutants in plumes around the immediate vicinity of the major oil sands surface mining facilities...

The Canadian Air and Precipitation Monitoring Network (CAPMoN), operated by Environment and Climate Change Canada (ECCC), is designed to study the regional patterns and trends of atmospheric pollutants such as acid rain, smog, particulate matter and mercury, in both air and precipitation. The...

Ammonia (NH3) data were collected at regionally representative Canadian Air and Precipitation Monitoring Network (CAPMoN) sites. Radiello brand passive samplers were deployed at 2 or 5 m above the ground for two week periods and analyzed by the National Atmospheric Deposition Program (NADP)...

The datasets and maps are associated with a research study. Annual total (dry + wet) deposition fluxes of nitrogen (nitric acid, nitrate and ammonium) and sulfur (sulfur dioxide and sulfate) were determined at 15 Canadian Air and Precipitation Monitoring Network (CAPMoN) sites from 2000 to 2018....

This data collection contains particulate metals data measured at sites in Canada. For additional data on pollutants in air, also see the data collection of Anthropogenic Organic Pollutants in Air. For additional data on metals, also see the data collection of Metals in Precipitation.

Total gaseous mercury (TGM) data are currently collected by Environment and Climate Change Canada at two Wood Buffalo Environmental Association (WBEA) Air Monitoring Stations (AMS). Preliminary, hourly averaged TGM data from the oil sands region are available for: WBEA AMS 6 - Patricia McInnes,...

This data collection contains air concentration data (in both gas and particle phases) of anthropogenic organic pollutants in air (AOPA). Some of the AOPAs in air reported in this data collection, are considered toxic substances (e.g. polychlorinated biphenyls, PCBs; polycyclic aromatic...

Measurements of gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM) and particulate bound mercury on PM2.5 (referred to as PBM2.5) were collected by Environment and Climate Change Canada from August to September 2013 at the Wood Buffalo Environmental Association (WBEA) Air Monitoring...

Measurements of gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM) and particulate bound mercury on PM2.5 (referred to as PBM) are currently collected by Environment and Climate Change Canada at a Wood Buffalo Environmental Association (WBEA) Air Monitoring Station (AMS)....

Total gaseous mercury (TGM) data are collected by Environment and Climate Change Canada at two Wood Buffalo Environmental Association (WBEA) Air Monitoring Stations (AMS). The instrument at WBEA AMS 11 was relocated to WBEA AMS 13 in Spring 2014. TGM data from the oil sands region are available...

Ambient air is sampled daily, with a nominal 24-hour sampling period, on a Canadian Air and Precipitation Monitoring Network (CAPMoN) sequential sample head located 10 meters above ground. Air is drawn through a three-stage filter pack consisting of 47-millimeter Teflon, nylon and cellulose...

Long Term Air Pollutant and Meteorological Monitoring at Fort McKay’s Oski-ôtin site: Validated data Continuous monitoring of multiple air pollutants along with meteorological conditions began in Fort McKay at the Oski-ôtin site in August 2013. The purpose of Oski-ôtin’s enhanced monitoring is to...
