Federal

Regionally representative data from Canada and the U.S. collected using wet-only precipitation collectors including Canadian federal and provincial networks (past and present) and U.S. historical networks (for data not available elsewhere). Data product types include major ions (also known as acid rain), mercury (Hg), and toxic substances such as metals, organic compounds, Polycyclic Aromatic Hydrocarbons (PAH) and Polychlorinated Biphenyls (PCBs).

Trace gas data sets measured by Canadian and U.S. ground-based monitoring networks from 1982 to the present including non-methane hydrocarbons (NMHC), ozone (O3) and total gaseous mercury (TGM). Included are Canadian federal and provincial networks (past and present) and U.S. historical networks (for data not available elsewhere). These data sets are associated with various networks that monitor a variety of trace and reactive gases. Non-Methane Hydrocarbons were measured and monitored in a study at Egbert, Ontario at the Centre for Atmospheric Research and Experiments, CARE.

Particle data from Canadian and U.S. ground-based monitoring networks from 1982 forward include the following:

  • Aerosol Optical Depth (AOD);
  • Aerosol Size Distribution;
  • Aerosol Number;
  • Aerosol Chemical Composition;
  • Particulate Matter Mass;
  • Particulate Matter <= 2.5 microns (PM2.5);
  • Particulate Matter <= 10 microns (PM10);
  • Particulate Metals.

For further information about Atmospheric Particles Data, see the Monitoring of Atmospheric Particles_Metadata.pdf file. These measurements help scientists understand the linkages between aerosol chemical composition, aerosol radiative properties, cloud formation and precipitation.

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.

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 (Schroeder and Munthe, 1998). Reactive gaseous mercury is thought to consist of compounds such as HgCl2, HgBr2, Hg(OH)2 (Lin and Pehkonen, 1999), although the exact composition is unknown.
