Air Quality Data
Air quality is known and valued to ensure clean, healthy air for today and tomorrow.
The Palliser Airshed Society (PAS) was established in the Spring of 2003 to monitor ambient air quality in the Medicine Hat / Redcliff region and has expanded to cover the southeastern portion of the province. PAS currently maintains three continuous monitoring sites (Medicine Hat, Brooks, and Taber) as well as 16 passive sampling sites distributed throughout the airshed.
Of the two continuous monitoring sites, the Crescent Heights (Medicine Hat) station provides real time data or NO2/NOx, SO2, O3, CO, THC, and PM2.5 and Meteorological Data. In addition, the two sites serviced by the portable airpointers, currently located in Brooks and Taber, provide real time data for NO2/NOx, O3, and PM2.5.
Monthly Data available from the passive sites includes NO2, SO2, and O3 levels up to March 31, 2017. On advice from the Environmental Monitoring and Science Division – Alberta Environment and Parks, determination of O3 (ozone) by passive sampling was discontinued beginning April 1st 2017, as ozone levels remain ultra low and current passive monitoring methods cannot discern a relevant baseline. The passive network continues to monitor NO2 at 16 sites and SO2 at 8 sites within the airshed.

* Generation of real-time data may take a couple of minutes, please be patient. Large date scopes may time out while loading data; please keep searches within ~6 months time frame.
Collecting and Reporting Ambient Air Data
PAS operates infrastructure and reports Ambient Air Data in compliance with Air Monitoring Directive (AMD) and alignment with South Saskatchewan Regional Plan (SSRP) and The Canadian Ambient Air Quality Standards (CAAQS).
