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.
