The monitoring stations are operated in accordance with Alberta’s Air Monitoring Direc- tive. All data undergoes a rigorous quality assurance and quality control program, includ- ing daily equipment checks, monthly multipoint calibrations, and annual government audits conducted by Alberta Environment. PAZA also conducts frequent data review for variances and trends.

The data is compared against Alberta Ambient Air Quality Objectives (AAAQO) as defined in the Alberta Environment Protection and Enhancement Act. The AAAQO are intended to provide protection of the environment and human health. PAZA reports any exceedences of AAAQO and submits monthly and annual air quality monitoring reports to Alberta Environment.

PAZA also provides near instantaneous air quality data for public viewing online. For the calculation of the Air Quality Index (AQI) measurements, PAZA submits up to the hour data to Alberta Environment. The AQI is updated hourly, 24-hours-a-day, and can be viewed on our website and the Alberta Environment website.
