This AMS was originally part of the air monitoring network operated by Suncor. It contains analyzers that continuously measure SO2, H2S, and THC.
On the left hand side of the AMS is the lower portion of a tower that is 75 m high. At heights of 20 m, 45 m, and 75 m there are sets of instruments that measure temperature, horizontal wind speed and direction, and vertical wind speed. There is an additional temperature device at a height of 2 m.
H2S analyzers are based on a scientific measurement principle (fluorescence after thermal oxidation) specified by AENV in the Air Monitoring Directive (AMD). The H2S analyzers also oxidize other sulphur compounds that are fluoresced and read as H2S. The analyzer can therefore over report actual H2S concentrations.
Within the WBEA network, H2S is measured at some AMS's and Total Reduced Sulphur (TRS) is measured at others. TRS analyzers use the same measurement principle (fluorescence after thermal oxidation) as H2S analyzers, but operate at a different oxidizing temperature. The choice of analyzer for each station is mandated by Alberta Environment Reporting Requirements in operating approvals, and by the AMD.
The Alberta Ambient Air Quality Objective (AAAQO) for H2S is based on odour perception.

All air quality monitoring data displayed on this site by the Wood Buffalo Environmental Association is directly from monitoring equipment output signals. Displayed data is generally indicative of ambient conditions, however, it has not been reviewed, validated, nor processed for baseline drift and other fluctuations by qualified technicians. Final processed and validated data values may vary from values displayed on this site. A displayed value of 'n/d' indicates air monitoring data is not available at the corresponding time due to scheduled maintenance and/or instrument calibration. Charted data is locked to the range of the analyzer by default, and can be unlocked by the appropriate control.

Historical Monitoring Data
PLEASE NOTE: When ambient concentrations of any pollutant WBEA measures exceeds the Alberta Ambient Air Quality Objective, WBEA has an immediate Reporting Protocol that is put into action. WBEA analyzers continuously monitor ambient air, and in the event of an exceedence the following steps are taken:
1 - The data collection system automatically sends out alarm notifications to WBEA personnel and an independent third party alarm monitoring company.
2 - The alarm company acknowledges the incoming alarm and reports the data and supporting information such as wind conditions, locations, time, etc, to Alberta Environment & Sustainable Resource Development (AESRD) in real time, or as soon as becoming aware of it.
3 - As the provincial regulator, AESRD uses the data and information from WBEA to follow up as appropriate.
