The Regional Air Quality Deterministic Prediction System FireWork (RAQDPS-FW) carries out physics and chemistry calculations, including emissions from active wildfires, to arrive at deterministic predictions of chemical species concentration of interest to air quality, such as fine particulate matter PM2.5 (2.5 micrometers in diameter or less). Geographical coverage is Canada and the United States. Data is available at a horizontal resolution of 10 km. While the system encompasses more than 80 vertical levels, data is available only for the surface level.

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/

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 Station (AMS) 13 – Fort McKay South, and at WBEA AMS 4 – Buffalo Viewpoint. Monitoring resumed at WBEA AMS 13 in September 2014 with two speciated mercury instruments and is ongoing. One speciated mercury instrument monitors GEM, GOM, and PBM2.5; the second speciated mercury instrument monitors GEM, GOM, and mercury on PM10 (referred to as PBM10). These data are the first atmospheric speciated mercury measurements to be reported in the oil sands region.

A cross-over study was conducted among 42 healthy adults during the summer of 2010 in Ottawa, Canada. Participants cycled for 1 hour along high and low traffic routes and ultrafine particles (UFPs) 0.1um in aerodynamic diameter, particulate matter (PM2.5) 2.5 µm in aerodynamic diameter, and black carbon were measured along each cycling route. Ambient nitrogen dioxide (NO2) and ozone (O3) levels were recorded from a fixed-site monitor.

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 for better understanding of the global distribution, sources and trends of pollutants. Using satellite data for the oil sands region, high-resolution air pollutant maps show distinct concentrations of NO2 (Figure 1a) and SO2 (Figure 1b) over an area (roughly 30 km x 50 km, or 19 miles x 31 miles) of intensive oil sands surface mining. The map shows that NO2 concentrations are significant and are comparable to measurements made over large, individual sources such as coal-burning power plants.

Hourly ambient nitrogen oxides (NOx, NO2, NO) data in parts per billion from provincial ambient air quality monitoring stations across Nova Scotia up to the end of 2021. This air quality station was established to replace the "Halifax Vogue" air quality monitoring station which ceased monitoring at the end of 2017. The Halifax Vogue station was less than 1 block away from the new "Halifax Johnston" station.
