Hourly ambient sulphur dioxide (SO2) 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.

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).

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.

Measurements of the concentrations of air pollutants (Nitric oxide + Nitrogen dioxide - NOx, Sulfur dioxide - SO2, Ozone - O3 and PM2.5) were made at Resolute (2013-2017), Cape Dorset (2013-2017) and Pond Inlet (2018-), in addition to basic meteorology (wind speed and direction, temperature, humidity). The primary objective was to investigate the impact of increasing ship traffic on the air quality in northern communities, in support of Arctic Air Quality model development as well as policy work for the International Maritime Organization. A secondary objective was to evaluate the impact of community diesel power plants on the local air quality. Data consists of quality-controlled 1-minute averages, calibrated in post-processing against traceable standards.

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 filters. Particulate Cl-, NO3-, SO4=, NH4+, Na+, K+, Ca++ and Mg++ are collected on the Teflon filter, gaseous HNO3 and a small amount of SO2 are collected by the nylon filter, and gaseous SO2 and residual HNO3 are collected by the K2CO3-impregnated cellulose filter. Filter loadings determined by laboratory extraction and analysis are blank corrected and divided by calibrated sample air volume to get atmospheric concentration in micrograms per cubic meter at International Union of Pure and Applied Chemistry (IUPAC) standard temperature and pressure.
