The Nitrogen Scoping Study consisted of 14 different field campaigns, each of 3-7 weeks duration undertaken between November 2001 and March 2005 at 8 sites of the Canadian Air and Precipitation Monitoring Network (CAPMoN). The objectives of the study were: (1) to characterize the ambient concentrations of oxidized and reduced nitrogen species at CAPMoN sites, (2) to estimate the contribution of the different nitrogen species to nitrogen wet, dry and wet+dry deposition at CAPMoN sites (with a view to understanding which nitrogen species should be added to the CAPMoN suite of measurements) and (3) to measure the size distribution of various inorganic ions in particulate matter at CAPMoN sites. The resultant data sets provide short-term characterizations of air quality at the 8 rural/remote locations in Canada and are provided in collaboration with the National Atmospheric Chemistry (NAtChem) Database and Analysis Facility of Environment and Climate Change Canada.

The Pacific 2001 Air Quality Study (PAC2001) was conducted from 1 August to 31 September, 2001 in the Lower Fraser Valley (LFV), British Columbia, Canada. The study consisted of a number of research projects organized to address several issues related to ambient particulate matter and ozone. A special issue of Atmospheric Environment [Vol. 38(34), Nov 2004] describes the study objectives (Li, 2004) and the study results.

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 hydrocarbons, PAHs; some flame retardants; and some organochlorine pesticides, OCs). These data come from monitoring sites in Canada.

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 conditions, GEM (or Hg0) is the predominant species in the air (~95-99%), while RGM and PBM concentrations are typically two orders of magnitude lower, i.e., <5% of the total atmospheric mercury concentration. Reactive gaseous mercury is thought to consist of compounds such as HgCl2, HgBr2, Hg(OH)2 although the exact composition is unknown.

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).

At all locations the TGM measurements were made using automatic Tekran ® 2537 mercury vapour analyzers (described in detail in Poissant, 1997). The air is typically sampled at flow rates between 1.0 and 1.5 L/min (depending on location) and is passed through a Teflon filter (47 mm diameter; 0.45 µm) at the sample line inlet to remove particulate matter. Inside the analyzer, the mercury in the sample air is pre-concentrated before analysis by amalgamation on gold cartridges (5-30 minute concentration time). Mercury is removed from the gold cartridges by thermal desorption and is detected using Cold Vapour Atomic Fluorescence Spectrophotometry (CVAFS).

This Alberta Official Statistic summarizes annual results of calculations of air quality index values as calculated by quality-assured and quality-controlled hourly ambient air quality data. It reports on the percentage of the time the air quality index was rated as Good. It also provides an overview of the index, the substances that are used in its calculation, and the causes of poor air quality both in a general sense, and with specific reference to actual events in the years presented.

Hourly ambient ground-level ozone (O3) data in parts per billion from provincial ambient air quality monitoring stations across Nova Scotia up to the end of 2020. 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.
