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 chromatograph system. Data were collected continuously since from March, 2001 to February 2011. The objectives of the study were to collect speciated hydrocarbon data for assessing clean and polluted air masses that arrive at the site to track long term trends in of NMHC mixing ratios in this quickly developing rural area to provide input for chemical transport models and other special studies carried out at the site, and to provide a long term intercomparison data set with co-located NMHC canister sampling carried out every third day by the National Air Pollution Surveillance Network (NAPS).

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 Network (CAPMoN) and studies such as those from Alert, NU and Mount Sutton, QC are also included within the published data sets. In CAPMoN, measurements are made every minute and averaged at five minute intervals.
On November 29, 2021, the Minister of Justice and Attorney General of Canada introduced a bill to criminalize so-called conversion therapy practices in Canada. Conversion therapy is a practice that seeks to change an individual’s sexual orientation to heterosexual, to change an individual’s gender identity to cisgender, or to change their gender expression to match the sex they were assigned at birth. This bill is similar to former Bill C-6, which was adopted by the House of Commons in the previous Parliament, but with one important difference. It expands on the previous proposed legislation to protect all Canadians—regardless of their age—from the harms of conversion therapy practices and to promote the dignity and equality of lesbian, gay, bisexual, transgender, queer and Two-Spirit (LGBTQ2) persons.
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.
On-going monitoring of the total column ozone and spectral ultraviolet radiation (UV) in Canada is carried out by the Canadian Brewer Spectrophotometer Network (CBSN). The data are used for periodic assessment of the state of the ozone layer, satellite data validation, and in forecasting ECCC’s UV Index. The UV Index values are derived from spectral UV measurements. All locations make total column ozone and spectral UV measurements using Brewer spectrophotometers.
This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of hydrostratigraphic unit (HSU) C2, which contains the majority of fine-grained materials in the Neogene-Quaternary succession of the Sylvan Lake sub-basin and is the top boundary of the model domain. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of steps taken to produce the structure grid.
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.
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.
