Continuous air quality data
Currently, the Alberta Air Data Warehouse provides reports for data collected from continuous air quality monitors.
Data flags are used as an indicator of data validity and to provide additional information about the data. Flags may be used to indicate data that are anomalous based on quality control and quality assurance or to explain why a measurement is missing. By default, the reports generated include only valid data as defined by the flags associated with the data point. There are also options to show all available data and associated flags in the report.
Please note: We are aware that some users are experiencing difficulty with reports. This is a result of technical changes required to modernize the database originally developed 20 years ago. We are working on correcting these issues and apologize for any inconvenience.
The data has undergone quality control and assurance, and can be searched by station name or parameter measured at:
Station information and status
For a list of continuous air monitoring stations, including latitude/longitude, parameters measured, and station status, see: Station Information and Status.
Reference data, such as the definitions of the flags and which are associated with valid data, as well as other additional information can be found on the Reference Table file under the Ambient XML Schema section of the following web page: ETS Support and Online Learning: Air.
Links to additional datasets
Data collected by the Alberta core long term deposition network are stored in the National Atmospheric Chemistry (NAtChem) database. NAtChem also includes data on air quality and deposition at rural or remote locations, collected using a variety of measurement platforms across Canada.
The National Air Pollution Surveillance (NAPS) program provides air quality data across Canada. The NAPS program includes the collection of 24-hour integrated samples once every three or six days at select urban locations in Alberta.
These samples are analyzed to determine the composition of particulate matter in the air and the concentrations of volatile organic compounds.
