The Canadian Ozonesonde Network measures vertical profiles of ozone from ground level up to 36 km altitude across Canada. The objectives of the network are to provide long-term stratospheric and tropospheric ozone data for periodic assessment of the state of the ozone layer, to validate satellite...

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,...

The Special Studies presented on this site are special measurement campaigns (with durations of several weeks to several years) carried out by the Air Quality Research Division of Environment Canada and its government, university and industry collaborators. The Special Studies data sets consist...

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...

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...

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

In October and November 2015, ground-based air measurements of pollutants were made from two mobile laboratories in southeast Saskatchewan in an area within a 50 km radius of Stoughton, Saskatchewan by scientists of the Air Quality Research Division, Environment and Climate Change Canada....

Ground level ozone and meteorological parameters were measured at the Mount Sutton research site from October 1986-June 2008. The main objectives of these measurements were: to characterize high elevation (845 m.a.s.l.) ozone levels in this rural region; and 2. to determine long term ozone...

The Great Lakes Basin (GLB) Monitoring and Surveillance program under the Chemicals Management Plan (CMP) of Environment and Climate Change Canada (ECCC) has been operating since 1990 as a result of provisions called for in the Great Lakes Water Quality Agreement (GLWQA) between Canada and the...
