The Regional Deterministic Air Quality Analysis (RDAQA) is an objective analysis of surface pollutants which combines numerical forecasts from the Regional Air Quality Deterministic Prediction System (RAQDPS) and hourly observational data from monitoring surface networks over North America in order to produce a better description of the air quality at every hour. Chemical constituents include 03, SO2, and NO2 gases, as well as fine particulate matter PM2.5 (2.5 micrometers in diameter or less) and coarse particulate matter PM10 (10 micrometers in diameter or less). Geographical coverage is Canada and the United States. Data is available only for the surface level, at a horizontal resolution of 10 km.

Hourly values of AQHI (Air Quality Health Index) constituents (O3, NO2, PM2.5), other selected trace gases (SO2, H2S), and PM1 and PM10 mass concentrations collected at the Sable Island Upper Air Station, Sable Island, Nova Scotia, Canada. Data is available from January 2017, and is updated at least annually. Supplemental Information

Lower Detection Limits (LDL) 0.4 ppbv for NOx, SO2, H2S, 1 ppbv for O3, 0.1 ugm-3 for PM (particulate matter). Error estimates:

+/- 10% and +/- 0.2 ppbv for NOx, SO2, H2S (except +/-20% NOx January 2017);

+/- 10% and +/- 1.0 ppbv for O3;

+/- 3% for PM2.5 (from manufacturer).

Air emissions from oil sands development can come from a number of sources including industrial smokestacks, tailings ponds, transportation, and dust from mining operations. Air quality monitoring under the Joint Canada-Alberta Implementation Plan for the Oil Sands is designed to determine the contribution of emissions from oil sands activities to local and regional air quality and atmospheric deposition both now and in the future. Ambient air quality data include:

  • Filter Pack (24-hour integrated concentrations of particle-bound SO2-4, NO-3, Cl-, NH+4, Ca2+, Mg2+, Na+, K+ and gaseous SO2 and HNO3 collected daily by the Canadian Air and Precipitation Monitoring Network)

  • Total Gaseous Mercury (hourly mixing ratios measured by the Canadian Air and Precipitation Monitoring Network and Prairie and Northern Region)

  • Atmospheric speciated mercury (Hg) (2-hour average concentrations of gaseous elemental Hg (GEM), reactive gaseous Hg (RGM), and Hg on PM2.5 (total particulate Hg - TPM)

  • Comprehensive set of measurements collected from an aircraft (various time resolutions) covering an area of 140,000 km2 over the oil sands region

  • Comprehensive set of measurements collected from the Fort McKay Oski-ôtin monitoring site

  • Ozone (hourly mixing ratios measured by the Canadian Air and Precipitation Monitoring Network)

  • Ozone Vertical Profiles (ozone mixing ratios as a function of height) measured by the Canadian Ozone Sonde Network

  • Aerosol Optical Depth (measure of the degree to which the presence of aerosols in the atmosphere prevents the transmission of light, from the ground to the top of the atmosphere) measured as part of the AErosol RObotic CANadian (AEROCAN) network

  • Satellite overpass data have a relatively high spatial resolution over the Oil Sands region to produce images and geo-referenced data of nitrogen dioxide (NO2) and sulphur dioxide (SO2) “vertical column density” (which correlates with surface concentration)

From August 10 to September 10, 2013, ground-based monitoring was significantly augmented at the Fort McKay South site (AMS13) to measure additional air pollutants and meteorological properties beyond what was available from the established long-term air quality monitoring in the area. This air monitoring study, undertaken in parallel with measurements from an aircraft flying over and downwind of the oil sands, was designed to gain a clearer picture of the mixture of air pollutants produced from different oil sands related activities and how they react and are transported in the atmosphere. These data are used to improve the capability of air quality models to determine current and future air pollutant levels and amounts of atmospheric deposition of pollutants over and downwind of the oil sands region. Periods of elevated pollutant concentrations were observed; however, none of these surpassed the current short duration (hourly, 8 hour or 24 hour) federal and provincial standards.

This dataset provides a summary of annual air pollution statistics from 1995 to the current available year for six air pollutants: * Carbon Monoxide * Oxides of Nitrogen (NO, NO2, NOx) * Ozone * Fine Particulate Matter (PM2.5) * Sulphur Dioxide * Total Reduced Sulphur The annual statistics include percentiles, mean, maximums and also indicate the number of times an air monitoring station exceeded an Ontario annual ambient air quality criteria, where applicable. This information is also available in the annual Air Quality in Ontario Reports. The hourly air pollutant concentration data is posted in near real time on the Air Quality Ontario website: http://www.airqualityontario.com/

Health Canada undertook a health risk assessment of sulphur dioxide (SO2) in order to update the available information on adverse effects of SO2 to human health, determine recent Canadian SO2 exposure levels, and to inform the revision or development of Canadian ambient air quality objectives/standards.
