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...

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...

This data collection contains metals data in precipitation measured at sites in Canada. For additional data on pollutants in precipitation, also see the data collection of Anthropogenic Organic Pollutants in Precipitation. For additional data on metals, also see the data collection of...

The Non-Methane Hydrocarbons (NMHC) Measurements Study was a continuous measurement program carried out at the Centre for Atmospheric Research Experiments (CARE) at Egbert, ON. Approximately 30 C2 to C8 hydrocarbons (in gaseous form) were collected and analyzed every three hours by an automated,...

Ground level ozone measurements, sometimes referred to as in situ measurements are those measurements that occur close to the ground, i.e. within the boundary layer which is approximately 1 kilometre in height. Ongoing network measurements from the Canadian Air and Precipitation Monitoring...

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...

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...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Air quality indicators track ambient concentrations of fine particulate matter, ground-level ozone, sulphur dioxide,...
