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...

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...

These data are associated with the following two publications: Zhiyong Wu, Staebler R., Vet R., and Zhang L. (2016), Dry deposition of O3 and SO2 estimated from gradient measurements above a temperate mixed forest. Environmental Pollution, 210, 202-210, DOI: 10.1016/j.envpol.2015.11.052 and...

Ground level ozone (GLO3) was measured at the Alert, Nunavut research station (82º28’N, 62º30’W) from 31 December 1991 to 31 December 2003. These measurements were conducted to: 1. determine a long term trend in background ozone, and 2. to understand the annual appearance of surface level ozone...

Systematic air quality measurements were made in the study region of Toronto during the 2015 Pan-Am games (July 14th – July 29th). These measurements were done using the mobile lab CRUISER (Canadian Regional and Urban Investigation System for Environmental Research) to identify emission sources...

Measurements of the concentrations of air pollutants (Nitric oxide + Nitrogen dioxide - NOx, Sulfur dioxide - SO2, Ozone - O3 and PM2.5) were made at Resolute (2013-2017), Cape Dorset (2013-2017) and Pond Inlet (2018-), in addition to basic meteorology (wind speed and direction, temperature,...

The atmospheric monitoring subcomponent of the Northern Contaminants Program (NCP) studies long-range transport of anthropogenic organic pollutants in air (AOPA), mercury, and chemicals of emerging arctic concern from around the globe. This subcomponent includes three NCP Core Monitoring...

Precipitation samples are collected at a number of sites in Alberta by Alberta Environment and Parks. Samples are analyzed for select cations and anions as well as pH. Samples are collected weekly using an event-only precipitation sampling protocol. The specific monitoring objectives are to: (1)...
