This station was originally part of the air monitoring network operated by Suncor. The station is the orange building. It contains analyzers that continuously measure SO₂, H₂S, and THC.

On the left hand side of the photo 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.

Our 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 stations and Total Reduced Sulphur (TRS) is measured at other stations. 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 AENV Reporting Requirements in the Approvals to Operate a Facility and by the AMD.

The Alberta Ambient Air Quality Objective (AAAQO) for H₂S is based on odour perception.
