Information received in response to the data gathering initiative on certain cobalt-containing substances (2012). To increase transparency and to facilitate access to information on substances in commerce in Canada, the Government of Canada is providing the summary of the information received in...

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...

Measurements of gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM) and particulate bound mercury on PM2.5 (referred to as PBM) are currently collected by Environment and Climate Change Canada at a Wood Buffalo Environmental Association (WBEA) Air Monitoring Station (AMS)....

This notice applied to owners of facilities involved in certain activities and that used 1000 kg or more of dichloromethane per year. This notice was in effect from November 29, 2003, to December 31, 2005, for persons involved in pharmaceuticals and chemical intermediates manufacturing and tablet...

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...

Total gaseous mercury (TGM) data are collected by Environment and Climate Change Canada at two Wood Buffalo Environmental Association (WBEA) Air Monitoring Stations (AMS). The instrument at WBEA AMS 11 was relocated to WBEA AMS 13 in Spring 2014. TGM data from the oil sands region are available...

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 Homogenized Surface Wind Speed data consist of monthly, seasonal and annual means of hourly wind speed (kilometres per hour) at standard 10 metre level for 156 locations in Canada. Homogenized climate data incorporate adjustments (derived from statistical procedures) to the original station...

The Homogenized Surface Air Temperature data consist of monthly, seasonal and annual means of homogenized daily maximum, minimum and mean surface air temperatures (degrees Celsius) for 338 locations in Canada. Homogenized climate data incorporate adjustments (derived from statistical procedures)...

This map shows the projected change in mean precipitation for 2016-2035, with respect to the reference period of 1986-2005 for RCP4.5, expressed as a percentage (%) of mean precipitation in the reference period. The median projected change across the ensemble of CMIP5 climate models is shown. For...

Gridded monthly, seasonal and annual anomalies derived from daily total precipitation is available at a 50km resolution across Canada. The Canadian gridded data (CANGRD) are interpolated from adjusted precipitation (i.e., AHCCD datasets). Adjusted precipitation data incorporate adjustments to the...

Gridded monthly, seasonal and annual mean temperature anomalies derived from daily minimum, maximum and mean surface air temperatures (degrees Celsius) is available at a 50km resolution across Canada. The Canadian gridded data (CANGRD) are interpolated from homogenized temperature (i.e., AHCCD...

Monthly, seasonal and annual trends of daily minimum, mean and maximum surface air temperature change (degrees Celsius) based on homogenized station data (AHCCD) are available. Trends are calculated using the Theil-Sen method using the station’s full period of available data. The availability of...

Monthly, seasonal and annual trends of total precipitation change (millimetres) based on adjusted station data (AHCCD) are available. Trends are calculated using the Theil-Sen method using the station’s full period of available data. The availability of precipitation trends will vary by station;...
